When I first got these I almost returned them as the arch was so high. Here is an image??10/19/2020 I purchased a second waist trainer in a medium, this waste TRAINER by far is very comfortable, it fits well, the stretch is ?? I am not endorsed by this company???? I had the large and I am on the 3rd hook so I decided to buy the medium and put down until I am able to fit it. The white colour I tried got me another 15mins compare to the 2 black colour Ive tried. The strap that goes across the toes has a very sharp edge and has shredded my toes every time Ive tried to wear them. Helps me from dropping and/or scratching up my case. I am sorry but I cannot recommend this item to anyone. Both pairs basically fell apart with use. I ordered a 2xl and a 1xl big & tall6 foot tall and 280lbsThe 1xl big & tall fit me better.
