Great with vibram five fingers
I purchased these to use with my vibram five fingers. They do a great job preventing blisters on longer treks. I started using them less and less with the five fingers because my feet adapted to vibrams and blistered less. But now the injinjis are becoming useful again with one of my pairs of vibrams... I have machine washed a pair so many times that the inside bottom of them is becoming wrinkly and uncomfortable without socks. But when I wear the injijis, it makes them feel comfortable again.
