One of my GFs that's a tennis player with high arches says she uses Down Unders? I tried to google them for a link, but I just really wasn't getting the high arch correction. She said you can't buy them here in Mayberry. She bought them on vacation somewhere. I saw some of their stuff on Zappos, but dunno if those are the ones she means or not. Like you, she felt like the SuperFeets were not enough for her. I forgot to ask this of her, but the SuperFeet I ordered I went up a size to try and get them to fit the length of my arch. The correct size was too short. I read somewhere on here about others finding the same. I don't know if that would help or not.
