It wont the sape and actually will perfectly adapt to the surface. I love the look of the sandal and the color is perfect, a lovely lavender. I gave them 4 stars rather than 5 because I found 2 design issues that for me, make them less enjoyable than my other 3 pair of Crocs. On the plus side, theyre extremely comfortable in the ear, with a hook that fits over your natural ear fold and secures them in place. Despite the previously mentioned shortcomings (No pun intended) I was pleasantly surprised, then plat IMPRESSED at the sound quality, user interface, and available features in this unit. Theyre still working and Ill keep using them! I leave on my bench Olympic bar and about another 170lbs ( 2 x 35, 2 x 25, 4 x 10 and 2 x 5) on rack. These shoes run at least 2 sizes small. Ive been wearing clarks flipflops for forever. But so far so good with these and they?re super cute!
