I am not a heavy user, but I bought a pair of these (I think on Todd's recommendation, for a good value set) and have been extremely happy. I can't speak to sizing, beyond the simple advice: go try 'em on. I think I got mine at Joes (now closed) I think Outdoor Emporium has them, but calling around seems the wisest move...
