Good article, thank you.
Socks: I wear polypropylene liner socks (Fox River) in the Summer. They are cooler and lighter than any SmartWool or Darn Tough merino. There’s something slightly sus about that study. :) For sure, fabric weight is a confounding factor.
Orthotics: I get some metatarsal pain behind the big toe on my right foot from repeated footsteps on rocky trails. I have some knee injury on that side, so maybe I step differently. I try to land on heel and the outer edge of my foot, to no avail.
Rock plates help but are not a full solution.
I’ve tried several insoles. Sole brand has an insole with a metatarsal pad that is in the correct spot to help, but the pad is not thick enough to do the job. If I add a stick-on pad between the metatarsal and my arch (behind the metatarsal joint), then that prevents the pain.
It is annoying to find the correct location and to keep the pad in place. I found that 3m pads stick better than Dr Scholls.
Are there other techniques for metatarsal pain that I may be missing?
