i had a pair of Dynorooz that i bought about 4 years ago, i just purchased the Tour Ultras, I put the number 4 on the slide. I saw a post on hammerbowling.com and a guy mentioned having to cut the replacement slide. So im assuming that it comes in a sheet like you mention. I used to wear dexter before the last 2 pairs, and im not sure about the sst 8s but the 7s were garbage. 3 of my friends had them fall apart, and im pretty sure ill never wear anything but 3G ever again. Highest quality shoe out there In my opinion. all my friends and I have nothing bad to say about the Ultras. Great pair of shoes
