I switched from Lind's to Dexter recently, also. I went with the SST 6 LE shoes, and I had the same problem. The first change I found I had to make was with the heel. The heel that came on the shoe would not slide nearly as much as I was used to with my Lind's. The sole seemed fine, but I could feel the heel holding up the slide, at the line. I switched to the red leather heel on the Dexter's, which made a world of difference.
At first, I was trying the Dexter's for a game or so, and then comparing them to my Lind's. This did not work well. When I would switch from the Lind's to Dexter's, I would stick. When I would switch from the Dexter's back to the Lind's I would slide way too much.
Eventually, I just switched to the Dexter's and broke them in. I found that after about 3-4 games of using just the Dexter's I either got used to them and/or they started sliding a little more. My guess is it is a little of both. The Dexter shoe soles do not seem to slide as easily when they are new. Good luck. It is frustrating when your footwork does not feel right.
Just wanted to share my experience.
Thanks
