I bought a pair of these in the summer.  They were perfect--really worked well in the pool and in the dressing room at the pool. But, I washed them in some detergent that was too strong and they faded. They still worked fine, but I decided to splurge and get a new pair.  They were fine as I walked to the pool. When I walked out of the pool--I had to hold on to the walls to keep from slipping!  I almost fell three times in the changing room. Whatever you did to the soles has destroyed any traction whatsoever.  I will return these ASAP.  Speedo--you let me down.  BAD shoe, very bad shoe!
