Although this product was recommended by my physical therapist for plantar fasciitis, I am 5'2" tall with short legs. The strassberg sock did not fit me well. It cut off circulation to my lower leg and I had to stop using it. I cut the elastic on the top of the sock and it still cut off my circulation. I am not sure how it could fit people who are larger than I am. I do not have large calves. There needs to be a way to adjust the elastic and a sock to fit shorter people. It was also difficult for me to adjust to get the proper stretch in my foot. Although I had problems with the brace I got at my podiatrist's office, I wound up continuing to use that one. I think the Strassberg sock might be ok for taller people, but it definitely did not work for me.
