This is my first post. I'm just getting back into cycling after a many decade layoff. I'm 62 and weigh about 230, 5'7" tall or short, depending on your opinion I just purchased a Cannondale Trail 5. Right now, my wife and I are only riding on roadways and smooth gravel trails.
Here's my problem. I've got an artificial left knee. Due to the tendons being a bit tighter than the original, I can't get as much flex as I really need to pedal efficiently. This will change as I progress on my biking, but for now, my left foot keeps slipping forward until I'm pedaling on my heel. I can re-adjust my footing as I ride, but it's really inefficient.
I've tried riding with toe clips in the past and find them really dangerous for me, I can't seem to get my feet out of them very easily when I stop, so I'm not interested in using them. But I have never tried clipless shoes and pedals. I have no idea how easy it is to get in and out of them, and for that matter, if they would even work in my situation.
