I bought these to help with a small swelling I got on my foot recently. I've been wearing them for 28 hours now but they are not comfortable to wear, in fact these slippers are painful, painful enough to even take them off because they dig into the skin so much. The tip on them should be a little more rounded so that a normal person can wear them for more than 1 minute. I have already ordered a pair of slippers that do not hurt. I'm all for acupuncture and all, but they're getting a HARD pass from me.
