I wish I could wear VFFs. I tried some on last weekend but, alas my mutant webbed feet keep me from enjoying them (2nd and third toes on both feet are connected about 1/2 way to 2/3rds up!). So unless I get them surgically separated or somehow they start making them for us mutants, I'll stand back in envy.
(From what I could tell, then material felt great on the feet and I loved the bottoms. DAMN you feet!!)
