Skechers Gorun Razor 3 Hyper Review

The Skechers GOrun Razor has always been a do it all shoe.  Version one was very similar to other classic lightweight 4mm drop trainers.  Version two slimmed down and had a much faster feel to it.  The GOrun Razor 3 Hyper continues that tradition, further defining the lightweight trainer/racer category.  A new Hyper Burst midsole, a newly designed upper and a more durable outsole make this a great update.  Let's jump into the details.


Specifications (per Skechers Performance)
Weight: 6.4 oz (men's size 9)
Stack Height: 24mm / 20 mm
Drop: 4mm
Classification: Lightweight Trainer / Racer


FIT/UPPER

I typically wear a men's size 10 in most shoes and the Skechers GOrun Razor 3 Hyper fits fairly true to size.  The upper is higher volume throughout compared to most racing shoes but the laces respond very well to being tightened.  The upper no longer uses GOknit and instead a Ripstop mesh provides far more security.  The 3D printed overlays in the midfoot help lock the foot down very well when the laces are tightened.  The fit is typical Skechers with a little more room through the mid and forefoot.  However in the Razor 3 I had some additional pressure on my first toe as the mesh no longer stretches as much as the knit upper of version 2 (which is the trade off for more security).  This went away after a few miles and for those that are sensitive to this, know the upper will break in.


There is a mild heel counter in the rearfoot that provides some structure to the upper, but is very flexible and will not cause issues for those with sensitive heels.  I don't normal discuss insoles, but the Razor 3 Hyper has a glued in one.  While this is nice as there is absolutely no slippage even with quick turns, for those looking to put an orthotic or separate insole in the shoe, you can heat the glue on the underside up with a hair dryer and the insole will come out.  The perforated insole provides good traction with a sock on, but less than ideal comfort for wearing barefoot.  Thus this is not the most optimal shoe for wearing without socks.


RIDE/MIDSOLE

The GOrun Razor 3 Hyper is the first Skechers shoe to debut the Hyper Burst midsole.  This new midsole is both lightweight, cushioned and responsive.  The cushioning is of a shoe far heavier than the 6.4 oz listed weight but remains responsive thanks to the rebound of the sole.  Often time cushioned midsoles in lightweight shoes will bottom out as the pace picks up, but Hyper Burst remains consistent both new and as it ages.


The midsole is full length Hyper Burst so the ride is consistent no matter where you land.  The midsole is slightly more rockered than previous version with the return of the M-Strike design.  The beveled heel and cushioning provide a very smooth ride for any rearfoot landings.  The midsole is also flexible at the forefoot and combined with the gentle toe spring provides a smooth toe off as well.  The Razor 3 Hyper retains the 4mm drop of previous versions.  Given the midsole compression of the Hyper Burst, this may change depending on where you land (heel drop is dynamic, not static).


STABILITY

The Skechers GOrun Razor 3 has a unique last for a racing shoe in that the midfoot is not extremely narrow and the shape of the outsole is on the wider side.  This provides plenty of inherent stability along with the gently rockered M-Strike sole to move you in the right direction.  The forefoot is particularly wide and provides a very stable toe off.  Outside of those  aspects, the Razor 3 Hyper has no additional stability measures.  The sole is full Hyper Burst with no additional materials, so for those with stronger ankles and are used to these neutral rides, the Razor 3 Hyper will work well.


SPEED

The Hyper Burst midsole is a good combination of responsiveness and cushion.  The ride lends itself to both daily training, long runs and uptempo workouts.  This has been my go to shoe for tempo runs and faster long runs of all distances.  The Skechers GOrun Razor 3 Hyper works well for half to full marathon pace workouts and races.  For faster efforts, the amount of midsole slows the ride down a bit.  The lighter weight and Hyper Burst midsole do contribute to a faster feel but the ride provides more protection than all out speed.  This combination is what makes the ride so versatile compared to other shoes in this weight class.



DURABILITY

The new rubber outsole provides far superior durability to previous versions.  Combined with the long lasting Hyper Burst, the Razor 3 will last for some time.  I have over a 100 miles on one of my pairs and they have not lost any responsiveness and have minimal outsole wear (which is rare for me).  If anything, the midsole has firmed up slightly with time, making the Razor 3 Hyper more responsive with time.   Thus I would expect to get a similar number of miles in this shoe compared to most trainers (300-500) if not a little less due to the lighter weight materials.


THOUGHTS AS A DPT 

Hyper Burst is one of my favorite new materials on the market.  It manages to remain responsive, lightweight, cushioned and durable all at the same time.  This has been a difficult balance for companies to find.  Nike has the supposedly incredible ZoomX, which I have found to have terrible durability and stability.  The Adidas Boost is responsive, soft and durable, but very unstable and heavy.  361's QU!CKFOAM is very stable and responsive, but on the heavier side. Altra's EGO midsole is soft and responsive, but not the lightest either.  Saucony's EVERRUN is on the firmer and stable side, but lacks the high level of responsiveness I would expect.  Finding a balance can be difficult and it is challenging to do everything well.  The Skechers GOrun Razor 3 Hyper does a great job of covering all the bases.  It is lightweight at 6.4oz (men's size 9), it has a good fit and upper security, the sole is responsive and durable and there is enough midsole to provide a cushioned ride.  Hence why this shoe does so well over long distance workouts.  It may not be the best for all out speed, which is what happens to many of these distance shoes with the increase in cushioning, but this is definitely worth checking out as a do it all shoe.


WHO THIS SHOE IS FOR (Conclusion)

The Skechers GOrun Razor 3 Hyper is for those looking for a versatile lightweight shoe that can be used for long distance races to daily training.  The Hyper midsole provides enough cushioning to be used for mileage and is responsive enough to be used for uptempo workouts and distance racing.  The fit is higher volume for a racing shoe and once the forefoot breaks in a little provides plenty of room.  So for those looking for a do it all racer/trainer, take a look at the Skechers GOrun Razor 3 Hyper.


SIMILAR SHOES

Nike Vaporfly 4% - The most commonly requested comparison.  The Razor 3 is lighter, lower drop, does not have a plate and is more versatile (can be used easily for daily training).  The Vaporfly 4% is much higher off the ground, less stable, has a higher drop and the midsole has much more give to it.  Both make for great long distance racers.

Hoka One One Rehi - Very similar shoes.  Similar stack height, fit and weight.  However the Hyper Burst foam of the Razor 3 is far more responsive.  Whereas the midsole of the Rehi has far more give to it.  Thus the Razor 3 Hyper has a bouncy feel no matter where you land.

Altra Escalante Racer - The Razor 3 Hyper has slightly higher drop as the Escalante Racer is zero drop.  The fit is different as the Escalante Racer has a slightly snugger heel and wider forefoot.  The EGO midsole is also firmer due to the lower stack height.
