I had been using the Body Glove Riptide. The soles on my last ones seemed like the rubber had not cured. Got somewhat messy but lasted longer than I thought they would. These Speedo's seem just perfect for me but the sizing is different from Body Glove. The 13s were way too big and the 12s seem just a tad small -- but workable. Don't know how long they will last but they feel good and look good too. My feet say that these are OK!
