In the past, I have used socks. Athletic cotton socks did not give me quite the amount of slide that I was looking for, so I tried a dress socks that have a lot of nylon in them. It slid much further. I have also used stick-on Teflon soles, but the nylon mesh stick on soles worked the best for me. None of the stick-on soles work when the glue separates, comes off, and you end up doing a face plant on the approach. Now I wear Dexter SST8 with an S10 sole with a H7 heel. The H7 is a red felt heel that also slides. I cannot use the more traction heels, because I slide flat footed and the stickier heels cause my slide to stop, giving me the feeling of sticking. Do not use powder, because it is prohibited by USBC rules. I have been the victim of people using it, and almost fell a couple of times. Not fun!
