Just received item. Have not tried in the water yet. Bought another style from the same brand but different item numbers and different colors. The purple (this one) is women's size 10 from supreme seller inc. and costs $8.77 (July 2015). The purple one (this style) i received runs at least half an inch to 3/4 of an inch bigger and the insoles are glued on. The orange (other style) is from sunshine sells 4 less, womens size 10B(M) US, $11.52 and fits just right with removable insoles. Both have the &#34;WAVE&#34; brand and both are made in China. The bottom of the purple (this style) has a lot of little &#34;bumps&#34;, similar to a hiking shoe and the orange (other style) has flatter and bigger &#34;bumps&#34;. Both style have cord locks on the heel area to adjust the tightness of the cord to stop the shoe from slipping off the foot.
