Anyone else using Speedplay (X Series) pedals and have the after market Keep-On-Kovers Cleats Protection Covers? I have a pair of the Speedplay Coffee shop covers, but the idea of having the ones that stay on and protect and allow a bit better grip while walking even a short distance seems like a nice thing. But do they actually work or cause problems like harder to clip in or out? Using them for Road biking if it matters any....
