As a relative newcomer to cycling after a few weeks on bike i was persuaded but s/o to go clipless, got the road shoes and cleats, went on the trainer clip and unclipped fine. Went out on the road first time great in and out of pedals no trouble, but then for some reason had a long series of falling off and then i lost my nerve and confidence so had them removes and cages put back on. It was after this that i was reading lots of helpful posts here and discovered it was quite feasible to have mtb pedals put on, took the bull by the horns and bought some. They were great in and out so easy esp with the multi release ones, i have fallen off a few more times but not because i couldn't get unclipped, in fact i found when you start to fall your foot automatically releases from the multi-release ones. Good luck which ever way you go
Everyone on here is great, i have for a lot of support and help
