Interesting I just saw these for the first time this week. Example of one brand:
From the Gait Guys: They are pretty bulky but that could be a good thing, for some though they are just too bulky we have found.
Some people are running in them……We think our friend Dr. Mark Cucuzzella does (naturalrunningcenter.com) .
We use them with clients to walk around the house barefoot and get
used to engaging toes with a flat press (not gripping…like those silly,
flexor dominant promoting towel scrunch exercises !)
MIGHT help someone retrain some muscles if used in this fashion but just
wearing them does not produce magical results without some awareness
Keep in mind……forcing something doesn’t make it so………
spreading the toes with an object such as these doesn’t make them
automatically go where they are supposed to.
Most people need to relearn toe separation (actually abduction)…we
do alot of that in our offices….and then learn to bring the whole toe
flat to the ground with a good, firm toe press……..no
grip/scrunch/hyperflexion. The last thing we would ever want to do is
overfacilitate the long toe flexors (flexor digitorum longus) because
when we do, we inhibit other foot intrinsic muscles (ie. lumbricals).
