These shoes have never been climbed in, BUT, I have tried to wear them in at home. I used warm water to try and get them to fit because my research indicated these were the right size. (I have some instincts which everyone says size the same, but I think the increased asymmetry in the Furia S makes the equivalent size too small for my toes.) All this means is that a faint bit of the red colour has run into the yellow velcro strap and I can't return them to the retailer. Otherwise the shoes are like new as I have not managed to keep them on my feet longer than 5 minutes.
