Only had for one month and now it stop working! Living down here in the Deep South, I count on Teva sandals to keep my feet cool, well-supported, and up for our almost daily afternoon storms. 40 and found these from Brainwavs, which even comes in multiple color options as a bonus instead plain-Jane black! I would deduct one star, not because of the memory itself, but for the ease of installation. I like them a lot! I have been using it for 10 days (daily) and I love it. Well worth the price. I emailed customer service, and they just reiterated what was in the manual, and when I said this, they stopped replying. Debido a la forma cuesta mucho ponérsela, porque no tiene cierres ni broches. I have several pairs of crocs and wanted a simple, classic black pair of flats.
