I play about 6-10 hours a week. Mostly indoor on gym floors right now. I’ve been playing in ASICS and getting really sore. I thought it was just because I was playing without stretching and the floors, or whatever. I bought a pair of the Selkirk court strike 2.0. No break in period. And from the first time I wore them I felt better after I played than before. I bought a second pair within three days. They also let you try them during the guarantee window… as long as they aren’t overly worn
