I tried using a high-heel foot stretcher thing. So you might want to avoid that situation. I read the 1 star ratings before purchasing these sandals. Im a kayaker and hopping into my boat got a lot of water in it. Deswegen dachte ich, ich schreibe die erste Rezession. Wont buy this brand again. Fits a 28 30 waistline. So far, with possibly rough treatment, they go through about 2 pairs per 6 weeks. I do highly recommend these for use with your IOS, Android, mp3 player, PC or whatever and theyre not bad for watching movies and TV series, playing games as well as listening to your favorite music or audiobook. Also you are without a mic for who knows how long.
