PUMA Deviate Nitro Review
By Chief Editor Matt Klein


While carbon plated and new age foamed racing shoes have been developing for several years, plated training shoes are a relatively new concept. With designs similar to their racing counterparts but features, particularly weight, more in line with a training shoe, these shoes tend to blur several lines. The Puma Deviate Nitro was designed as a companion training shoe to the Deviate Nitro Elite (REVIEW), continuing to feature a Nitro midsole and a carbon plate but with a stiffer and less aggressive ride.

Specifications for the Puma Deviate Nitro (per Puma)
Weight: 9.4 oz / 268 g (men's size 9) 7.7 oz / 218 g (women's size 8)
Stack Height: 38 mm heel, 28 mm forefoot
Drop: 10 mm 
Classification: Carbon Plated Lightweight Trainer


RUNNING SHOE SUMMARY

The Puma Deviate Nitro is a carbon plated trainer for those wanting a stiffer shoe for mileage, uptempo and tempo days. A durable and grippy outsole provide excellent traction on road while a Nitro midsole provides protection and some mild bounce. The upper fits a bit long and loose in the heel, so for those wanting a little extra room length wise this shoe will work for you. The plate combined with the foam makes the Deviate Nitro best for uptempo days and workouts when you want to have the protection of a trainer and may compliment the Puma Deviate Nitro Elite well as a trainer/racer combo.



FIT (LENGTH / WIDTH / COMFORT)

The Puma Deviate Nitro fits me slightly long in my normal US men's size 10. I would only suggest going down a half size if you have narrow feet as the toe box tapers enough that it almost feels true to size. The lightweight mesh fits normal to slightly wide in the heel, with a normal fit in the midfoot and a taper in the forefoot. The heel fits loose and required me to lace lock the shoe to prevent slippage. There is a split heel counter in the rearfoot and the counters are fairly flexible. I did not have any trouble with my calcani in response to them. The heel collar has a slightly sharp edge to it, which required me to wear socks with this upper as it dug into my ankle. With socks I was fine, but without had skin irritation fairly quickly. There is additional padding around the heel counter for security, however this did not prevent my heel from slipping. The tongue is gusseted and has additional padding, so it stays in place very well. The laces are a bit thin, so when lace locking the shoe they dug into my ankle a little on my right side. They stayed secure, but the pressure into my ankle is noticeable the first mile of runs. Overall the upper is fairly flexible with just a little structure, requiring extra lock down for some and socks for all. 





PERFORMANCE (RIDE / SPEED)

The Deviate Nitro has a stiff and slightly firmer ride. The carbon plate is immediately noticeable, particularly at the forefoot/toe off. The ride while running easy feels too stiff, but begins to shine as the pace picks up. The heel bevel feels and looks like it is more centered, which combined with the stabilizing rearfoot TPU plate makes rearfoot landings a bit stiff. The 8mm heel drop is somewhat noticeable, although this may be due to the fact that the Nitro in this model feels more dense/firmer. When the pace picks up, the ride begins to improve. When the plate has enough force placed into it, there is a nice pop forward during toe off. This is not a softer ride like the Deviate Nitro Elite, but is firmer and more resilient. The best use of the Deviate Nitro has been during uptempo runs, tempo runs and fartlek runs. It is too heavy to be used for fast intervals, but is not relaxed/flexible enough for easy miles (unless you want a stiff shoe for easy miles). The traction and durability though are excellent. I have 30 miles in my pair and there is almost no wear on the outsole (it is dirty though). The PUMAGRIP does a great job on wet roads and I had no trouble cornering during an early morning hilly fartlek in the rain. 



STABILITY 

The Puma Deviate Nitro is a neutral shoe. However there are a few measures that provide mild stability. The TPU plate in the heel (the silver piece) does add rigidity and stability to the rearfoot. The midfoot narrows as the foot transitions forward, however the stiff carbon plate provides some torsional rigidity. The forefoot is very stable, sitting a bit wider and featuring the plate that reduces torsional rigidity. The slightly more medial heel bevel does not however add to stability. This offsets the stability from the TPU plate to a degree, making for a stiffer but neutral heel. The midfoot and forefoot plate may be too stiff for many, so some people may find themselves trying to move around it to get to toe off. The stability is better when moving at faster paces, but during easy paces I find my body trying to get around the plate, which is not optimal from a stability standpoint.

THOUGHTS AS A DPT / FOOTWEAR SCIENCE

When it comes to footwear prescription, we currently have no idea what the effects of running in carbon plated shoes are long term, let alone training full time in them. These are likely to be highly specific to each person, with some being great and others not doing as well. As we have discussed previously here, shoes are tools. The use of a carbon plate (or any plate for that matter) serves to stiffen the sole. Whether this influences performance is again person dependent, with older literature suggesting a 1% economy improvement at most with plates, newer literature suggesting that cutting the plate in half has no impact on the economy of certain types of racing shoes and that different amounts of stiffness in soles will benefit some runners and hinder others (Healey et al., 2021; Mcleod et al., 2020; Roy & Stefanyshyn, 2006). Additionally, there are many other components that influence sole stiffness and the perception of stiffness, including how soft or complaint the midsole, flex grooves, sole thickness and more. So whether a person can train full time in a running shoe with a plate will depend on several factors both within the shoe and especially within the person.

The Deviate Nitro joins a few other plated trainers including the New Balance FuelCell TC, New Balance Lerato, Nike Tempo Next% (composite plate), Saucony Endorphin Speed (Nylon plate), Mizuno Wave Rebellion (fiberglass plate), Skechers Maxroad 5 (carbon infused H-plate), Adidas Boston 10 (Rods), the North Face Vectiv series and a few others. The types of plates vary (carbon, composite, fiberglass, nylon, etc), but the function continues to be to stiffen to sole. Many shoes have had some form of a plate in them for years, with Mizuno's wave plate and On's speedboard coming immediately to mind.

Stiffening the sole can serve multiple purposes. It can certainly be a way to provide stability by increasing torsional rigidity. This can be helpful in shoes with very soft midsole materials to offset the instability of low durometer foams. Depending on the curve of the plate or the shape, motion can be facilitate or redirected in certain ways or into different parts of the foot. Biomechanically it can lengthen the lever arm, which in English means that with a high energy impact, more force may be translated in the direction of the plate. However there is a certain minimum force needed to optimally bend the plate. If you do not generate enough force, it is going to take extra force/work to get over the plate. Thus is my question regarding carbon fiber plated trainers. If you are going to put a stiff plate in a shoe that is meant for daily training paces and workouts, then it needs to have some degree of flexibility. This can also be accomplished with significant toe spring, which the Deviate Nitro has. However, the rocker starts later than necessary, make the ride more aggressive and stiff. The Puma Deviate Nitro is going to fit a very niche population of runners who want a very stiff and aggressive ride in a training/lightweight training shoe. Most others would be better off using shoes that either do not have a plate or have a bit more flexibility. As always, individual needs will varying.

RECOMMENDATIONS

I have several suggestions for the Deviate Nitro. I think its purpose is clear, but the execution needs some work. The upper is rough and not optimal, so I would suggest redoing the heel counter, removing the edges from the heel collar and optimizing the fit. The slightly long size makes me think I am hitting the plate wrong, which will totally change the ride of the shoe. The upper is also not very secure and attempting to lace lock causes some additional pressure on top of the ankle. In regards to the sole, I do like the Nitro foam, the TPU heel plate and the general design. However, I think the plate is too stiff for a training or lightweight training shoe. Similar to shoes like the Endorphin Speed or Wave Rebellion, I would either modify the plate material, increase the length of the toe spring or make it more flexible. This will make it more versatile for training and workout efforts, rather than being so stiff it only works for people that need very stiff shoes and those running faster.

WHO THIS SHOE IS FOR (Conclusion)

The Puma Deviate Nitro is for those who want a cushioned, carbon fiber plated lightweight trainer for uptempo mileage and workouts. While some may be able to use this shoe as a daily trainer if they want a very stiff ride, others will want to keep this for days when the pace is picking up. The upper fits slightly long and is not the most secure, so some experimenting with lacing and locking the shoe down will be needed in the heel before starting the run. The ride is protective but slightly firmer, best for those wanting a very stiff shoe or those wanting a training companion to the Puma Deviate Nitro Elite.


GRADING (SHOE CATEGORY)

Matt
Fit: B-/C+ (Slightly long fit, poor heel security, laces that cause extra pressure when secured and a heel collar that digs slightly into the skin. Best to wear socks with this shoe and try before you buy)
Performance: 
B (Stiff at slow paces, but shines at faster paces. A pure workout trainer)
Stability: B (Good heel and forefoot stability. Narrow midfoot and plate that is too stiff causes motion to redirect off the plate. So those who do not like shoes that are stiff may find this unstable in the midfoot)
DPT/Footwear Science: C+ (Good use of TPU plate in heel for stability, however carbon plate is too stiff for this shoe to really be a training shoe. May benefit from a longer toespring to facilitate forward motion)
Personal:  C+ (The subpar fit in the upper and overly stiff sole make this shoe difficult for me to reach for. Carbon fiber plated trainers have not worked well for me so far, but this shoe may be of interest if that is something that you do well in)
Overall: B-/C+ (Some issues with the fit and ride prevention this shoe from being as good as it has the potential to be. Puma is on the right track, but there are some things that need to be modified. Right now, this is best for those who aren't concerned about the fit and want a stiff carbon plated ride for easy days or a training shoe for workouts).

***Disclaimer: These shoes were purchased from Puma USA with a medical discount.  This in no way affected the honesty of this review. We systematically put each type of shoe through certain runs prior to review. For trainers and performance trainers, we take them on daily runs, workouts, recovery runs and a long run prior to review (often accumulating anywhere from 20-50 miles in the process). For racing flats we ensure that we have completed intervals, a tempo or steady state run run as well as a warm up and cool down in each pair prior to review. This systematic process is to ensure that we have experience with each shoe in a large variety of conditions to provide expansive and thorough reviews for the public and for companies. Our views are based on our extensive history in the footwear industry and years testing and developing footwear. If you are a footwear rep looking for footwear reviews or consultations on development, we are currently looking to partner with companies to assist, discuss and promote footwear models. Partnership will not affect the honesty of our reviews.
