I tried this product briefly but didn't attempt to run because I was nauseous. Good: The shoe itself is high quality, the heel support and mid support felt good although the mid felt a bit tight for me. The Bad: The toe box doesn't give much room, it's designed for a narrow foot. When I put the shoes on, my two outer toes immediately pressed hard against the mesh material. The lack of space was clearly visible on the outside of the shoe and it was clear that any use of this shoe would cause a great deal of discomfort. The shoe itself is ok, but the fit is not suitable for a wider foot.
