Doctors of Running (formerly Kleinruns DPT) began as a way for me (Dr. Klein) to share my thoughts and learn more about my major interests: footwear, biomechanics, physiotherapy, running and performance.  It continues to evolve to this day to meet the needs of those who contribute, those who read/visit and those looking for assistance.

Kaiser Southern California Manual Therapy and Sport Fellow

Dr. Klein began this blog as a Doctor of Physiotherapy student attempting to make sense of the world and share it with others.  He is a 1:11:11 half marathoner and 14:45 5k runner who runs 70-100 miles per week.  Matt has been running for almost 10 years, was an accomplished DIII runner including being the 2012 NWC 10,000m Champion and continues to compete at a moderate to high level.  He graduated from Western University of Health Sciences in 2016 with his doctorate, passed boards the same year  He completed his orthopedic residency at Casa Colina in 2018 and is currently completing a Manual Therapy and Sport Fellowship at Kaiser Los Angeles Medical Center in Southern California.  He has extensive history in the footwear world, working in the running industry for years prior to becoming a Doctor of Physiotherapy.  He has participated in and written research on footwear and running and continues to discuss and learn about those and more.  He currently consults for several footwear companies helping with the development of shoes with appropriate biomechanics in mind.  

He will continue to write about his experience as a Doctor of Physiotherapy, runner and footwear geek.  This will include a great deal of shoe reviews, training/racing updates, things he learns in clinic, exercises he is experimenting with, research and more.

He is currently a Skratch Labs Ambassador and looks forward to returning to highly competitive running in 2018.

As an extra, he is a talented fiddle player and composer with several tunes published in the Portland Collection volume 3.

  1. I am a 3 hour marathoner, who hasn't run in1 year due to neuroma surgery...my neuroma isn't truly fixed, my knee/it band is in pain--help me! And what is the right shoe for me??? #lasthope

    1. Hey BD. I have been trying to figure out how to address your question for a week.

      Since I have not been able to physically in person evaluate your running/walking form, complete injury history and more, I cannot truly treat you. Based on the little info you have given me, I would make sure you have a shoe with wide toebox that does not put ANY pressure on that neuroma. If you continue wearing tight shoes your neuroma will only get worse. I have had several patients who didn't change their footwear and movement patterns after having surgery and ended up having a neuroma return in a similar spot. A neuroma is a thickening of the nerve tissue in the nerves between the metatarsal bones usually in response to excess pressure. Narrow toe boxes put excessive pressure on those nerves by smashing the toes together. Additionally, based on your knee/IT band pain, I'm going to guess you have extremely weak hips. Whether that is coming from pain in your foot altering your movement pattern and you trying to load heavily at your knees instead of your foot due to pain, or if you have always had an underlying hip weakness, you need to strengthen you hip musculature. Most IT band/knee pain relates to poor loading at the knee joint from weakness elsewhere.. commonly from the hip musculature. That would also make sense if your hips are weak that you would have a neuroma because you are getting your propulsion from running excessively from your foot via excessive calf use, which can put heavy pressure on those metatarsals and your forefoot. Optimally your hips should contribute a great deal to forward propulsion in running equally along with the rest of the muscles and joints of your legs (quads, calves, hamstrings, glutes should contribute. When you over utilize one because others are weak, that's when injuries can happen), but sounds like yours are weak and you've been running for years with weaknesses, poor form and now your body can't compensate any more.

      I would go see a physical therapist or medical professional who specializes in running. Do not see someone who does not have experience with runners or is not a runner themselves. A physical therapist is going to be your best bet for truly changing your poor movement patterns that may have been creating these issues. Physical therapists are in charge of the movement system more than any other profession.

      So again those are my thoughts above. I am not treating you and you need to seek medical help. I have not physically examined you so do not rely on my words as medical advice. Those are just my thoughts based on what I have seen. I do not know if you may have something else going on because I do not have your full history. Please see someone and do not try to sort this out yourself. There is a reason medical professionals spend so much time learning before our professors let us out into the real world.

      Hope my advice provides some helpful insight.

      Thanks for reading a good luck.
