KEEP SHOPPING
It is very painful! I have a size 6 women's and where you put your feet in is huge! I either had to cram my feet all the way up to the front so that it doesn't pinch my heels off in the back or I tried pulling my feet all the way back into the slots for the heels but couldn't take the pain. Super disappointed.  Also it comes to a stop after each compression, not giving you that continuous massage. I only used it a couple times and my feet were even more painful to walk on.  Definitely returning this immediately.
