Most flip flops I've owned break at the strap between the toes or the soles wear out thin at either the toe or heel quickly. This is my second pair of Sanuk yoga sandals. My previous pair was the yoga mat style, which are nice but the straps on the Serenity are not as wide so they look more feminine. I left my last pair out on the patio in the sun for over a month and they hardened so I had to toss them, other than that I had them for several months and wore them everyday in the dirt, to town, etc. and they still looked good, even the little logo on the heel didn't wear off. I noticed with this last pair that they say manufactured in China which is too bad being that they are working the reputation of being eco-friendy and all.

5-9-12 EDIT: Ok so these are already going to have to be tossed soon. They did NOT hold up as well as the last pair. The foam is tearing apart and has worn down thin at the toe. The materials cannot be the same as the last, because I didn't get near as many mile out of them and they look like hell. They must have been outsourced since the last pair I had, that would definately explain the poor quality. I will not be buying Sanuk again.
