I’m not sure if they’ll help, but they are certainly easy to use
I’ve put clipless pedals onto the project bike so I can see if they’ll do anything about the balls of my feet cramping up when I ride a fast 200 or 300. I don’t know whether they will help there, but I do know that they’re pretty easy to use – I spent about 30 seconds practicing clipping and unclipping, then took the bike out for 13 miles of riding around East Portland without managing to kill myself even once.
