Honestly they are 10 times better as compression calves than the cheaper sonic welded version which just has the skin printed on the side. I got them from the UK because they are hard to find in the US. I have used (and still use occasionally) 2XU, Zensah, CEP and they are by far the best. If you can handle the wait and are patient, you will love them. High quality with stitched edges, fit like a champ and stylish. I even bought a pair of their hand warmers/compression sleeves with the same form factor ie patterns and colors and BOOM, same results. Love her and I think you will too!
