I'm coming to the realization that one of the many problems with a lot of modern running and trail shoes is an overly aggressive rocker in the front of the shoe. Do you agree?
The idea behind building an aggressive rocker into the shoe is to allow the walker to roll forward and to have the toes already in an up position for the next step. Stepping forward after all is a controlled fall.
However, in doing so the toes are lifted up and the metatarsal heads are exposed so that they take even more force than they are supposed to. We weren't meant to walk this way. Try lifting your heels up and walking with all your weight on your metatarsal heads – not pleasant. That's what women in high heeled shoes have to put up with every day.
The Montrail shoes I currently have, even though they are not the worst offender in this category, still have too much rocker in my opinion.
Last year I suffered inflammation in the metatarsal heads and I'm almost 100% certain by now that the issue was 1) overly aggressive rocker in both my running shoes and trail shoes 2) not enough width in the toe box of both my running shoes and trail shoes to allow for enough foot expansion. I've corrected the toe box width issue, which helped, but the aggressive rocker in my opinion is the remaining culprit.
I'm going to experiment with shoes with relatively low rockers. Unfortunately they're not that easy to find with all the marketing hype influencing shoe design.
The NB 876 for example appears to be a shoe with a relatively flat rocker. I'm hoping that La Sportivas, Innov-8 and perhaps Scarpa have some flatter shoes as well.
