Hi. I do not have Diamond Brite...but I have Pebble Tec. Pebble Tec may be rougher than Diamond Brite. The pool is a little over a year old. My feet are fine. It took me about 10 minutes to get used to it. I have not given it a thought since except that I am very glad I did it as it is beautiful. Good luck with your decision. Have a great day.

Mike
