Great product, great value.  I bought my first pair of Merrill Barefoot/Minimalist shoes about two months ago and have worn only this type structured shoe since with delightful results.  I have abandoned all my conventional shoes and own and wear 9 pair of the minimalist shoes and sandals.  My balance is steadily improving and the chronic numbness in my feet is steadily disappearing.

This technology my not work for everyone, but it sure has for these nearly 75 year old ex-trail runner's feet, legs and back.
