I purchased these on a whim, not expecting to love them but looking for something lighter weight than my regular shoes.  I am not a runner but do walk a lot and participate in classes at my gym.  I bought a half size larger after reading reviews complaining about blisters etc.

I put them on last night and my toes were able to really wiggle but the base of the shoe felt correctly sized, I decided to keep them after feeling that my toe really was at the end of the shoe and not wanting shoes so tight that they were uncomfortable.  I wore them last night and again this morning while walking my dog and can't believe how good they feel.  It really does feel like barefoot, only better than barefoot because there is some support under my heel. These are extremely comfortable shoes and very light weight.  They were pricey but I have never worn shoes this comfortable so I would say they are worth it!
