i wore dexters for 11 years including the sst 1's, 4's, 5's, and 6's. they are good shoes. no problems with wear and tear. i could never seem to find the right slide no matter what combo of heels and soles i tried. my dynorooz sport elite cabretta's are every bit as comfortable, stylish, and well built, plus i'm sliding better---almost perfect. the materials that the soles and heels are made of must be part of the difference. another reason may be that the shoe itself is slightly narrower which means there's less surface friction between the shoe and the approach. great shoes.
