The product i ordered was very good and of value, but the guide for how to measure for sizes and then what i received were correct as on the site but far too small for the size of my foot. I appreciate for it to work its got to be tight but it was even too tight to get half way on, i showed the site, dimensions to a physiotherapist who agreed that i had ordered correctly as directed to make sure and she couldnt get it on either, so in the end i told her to give it to anyone it would fit. To make it clear i have to point out that i had a stroke last yesar and thought it woulld be ideal, but i was wrong on this occasion, the product is good, but the sizing to me is what should be looked at especially if partially restricted as well by an illness.
