I've been climbing for ~9 months and purchased these shoes ~6 months ago. They were great. They fit well and stuck to almost anything. However now they aren't working that well for me. They have stretched a lot and are extremely flexible. The rubber around the toe has worn down a lot and isn't as sticky any more so i've noticed my feet slipping a lot. Also the profile of the toe has become a lot more rounded. I don't know if it's sloppy footwork on my part or a problem with the manufacturing process. Needless to say it's extremely frustrating when you need to trust your feet and find them giving out.
