Saw a work colleague from the States using one of these. Material is great. The best solution was a gentlemans idea of using a clip to hold it together and NOT move it. Came quickly. I cant recommend these highly enough! One of the things he loves best about these sandals is that they have deep heel cups, which help him with his posture. Sure it’s only $10, but I’ve bought better quality AirPod cases on amazon for around the same price. (I had only one usable arm due to shoulder surgery, but I was able to put it together in about 20 minutes). And always remember a corset will never work if its too big. 5-9 as I am an 8.
