I love grip studs. You guys should be paying me a sponsorship deal or something because I tell everyone here in Denver that I run with how great they are, and I post about it on Strava. Lol. I have noticed though that the lugs on many running shoes are not broad enough to support them well. Maybe one idea would be to give people some advice on what to look for in the bottom of a running shoe for ideal compatibility, or make a list of common running shoes that work well. For example, in addition to broad bugs, I think the shoe has to have a fairly thick sole and cannot have a carbon plate. That was pretty nice that someone called me when they were packing my order to make sure I had the correct installation tool. A+ customer service.
