There have no issues so far and everything works great. They straps have stretched out in only a few months that even secured down to the smallest option, still slip off all the time. Some people complain about how difficult they are to install, but I found that putting my fingers on the inside and stretching across made it very easy, took less than 2 minutes. I still have a pair of keen sandals from 2006. But are a fine pair of slippers, especially since you can take them outside. I quite like this brand. Gehen noch mehr kaputt, werde ich sie nicht noch einmal kaufen. No more using up one of my water bottle holders to house my phone - and you know I?ve fumbled and dropped my phone when accessing it from the water bottle holder! The crocs work very well on wet surfaces and I can now walk without worrying about falling. Read these reviews before u buy, good for a PA system for voice, but to listen to music.
