Customer feedback

Comments: Although I love injinji socks and have owned probably seven pairs, these socks were a disappointment.  They seemed just like regular injinji's to me except they had an extra style factor to them, so I went ahead and purchased them.  They seemed fine at first, but then I ran in them.  Every time the color of the sock changes, there is a little extra loose thread running off which is inside of the sock.  They bother my feet so I therefore almost never run in them.  I suppose you could turn them inside out, but I don't know if that would mess with the toe shape.  I do however strongly encourage buying a pair of injinji socks, just stick with a single colored pair.
