I have those Vibram 5 Fingers shoes and love them! I have the Bikilas LS (basically the speed shoes with elastic laces) and the men’s Spyridons. Definitely worth getting at that price! The Speeds are great pavement pounders or gym shoes (I use my Bikilas for doing Insanity, Tapout XT, P90X, etc). The Spyridons are great trail shoes. The sole is still flexible & very minimalist, but you don’t feel rocks, sticks, etc sticking into your foot (although you feel a bit of pressure).
Picked up a pair of the puma running shoes on a previous woot. Based on reviews on amazon I bought up 1/2 size and they are still quite narrow.
