I pretty much wear the Sansha footed or footless tights exclusively now. The fit can't be beat, and they are extremely comfortable.
New York Dancestore seems to have a monopoly on Sansha products, at least as far as the Internet is concerned. Maybe some retail stores carry them. I never shop for tights in stores, since they never have what I want, and the markup is awful. It's cheaper to order online. The only exception I make is when I need new shoes - I won't risk buying them on the Internet.[/i]
