Im sorry I waited for so long to get these. My headset was sliding back and forth on my head and it was obnoxious to wear. I suffer with plantar fasciitis and have lovely bunion as well and have been struggling to find a pair of sandals. Its a very nifty gadget that doesnt require set up apart from having to put in the batteries. Therefore, when I came back I ordered five bottles and one Moisturizer. Always ships on time and delivered intact. but you def cant travel around without some sort of support, itll shift around and fall out or something. My size is 10W but these 11M were great with a tiny bit of room too, so, can wear all day for work. Dont hesitate, buy them. Very comfy and was able to walk a mile in very nice.
