I wear VF exclusively as part of a
challenge/experiment I am doing over the next year. I've had a chance to do a lot of different kinds of activities in them. Some work well; others do not. BVFF seemed to be optimal during the few games of
b-ball that I played. Traction to the floor was great, and VFF kept me up on my toes where I could be a little more assertive in play. The one time I did come down on my heal, I was able to shift my weight quickly enough to avert injury or pain. I'm currently coaching badminton in them. No issues up to this point.
