My daughter wore them to skating class once and the seams at the top of the legs came undone. The sizing is a bit small compared to what it says it fits, but it's still the right size so it's nothing to do with stitching. Loose seams are also visible in the toe area. On the plus side, they have a nice lining and will keep your feet warm. It is very difficult to find tights with a good lining for skating.
