Janice, I have to applaud you for being so determined to ride in spite of your fibromyalgia. My mother suffers from that and arthritis. Her doctor recommends gentle exercise, but Mom won't do anything. I tell her that it'll be hard in the beginning then get easier and easier, but she seems to prefer living with the constant fatigue and discomfort. I wish you tons of good luck and many miles of enjoyable riding!
That said, I can't give you any advice on shoes or clipless systems. I have a pair of lightweight hiking-type shoes that I ride in, but I haven't had any trouble with hotspots. Regarding pedals, though, you're right that anything that holds your foot firmly to the pedal will definitely increase the power and efficiency of your stroke. You've got a few options for pedals, in order of result:
1) Clipless pedals and the appropriate shoes to go with them. Can be expensive (by my standards) and it seems you can only wear the shoes for biking. But, from everything I've read and heard, you'll get the best results going this route.
2) PowerGrips, which can attach to most pedals or can be bought pre-attached. You can wear any sort of shoes with them, from sandals to clod-hopping hiking boots. I just tried mine for the first time yesterday and noticed a tremendous difference. They take some adjusting the first time out, but they're great once you get them set just right.
3) Toe clips/cages. These also attach to pretty much any pedal and can be worn with a variety of shoes. They don't hold your foot as firmly to the pedal as the first two unless you're willing to adjust them each time you get on the bike.
I'll also say that you came to the right place for advice. I'm a newbie here, too, and have picked up some great tips. Everyone seems to really enjoy talking about bikes and riding, so it's a very comfortable place to ask questions.![]()
