Well, I switched to SPDs a few days ago. I've been thinking about it for ages, and been meaning to try them, but both the cost of a pair of shoes and the fact that I'd need to go and try them on somewhere was putting me off. But then there was the Aldi bike sale a couple of weeks ago, where they had cycling shoes for twenty quid. Even if they're not great shoes, at least it would give me a chance to try out SPDs. And with SPDs costing £16, it seemed silly not to.
The shoes really aren't great quality. The first pair I bought actually had the sole peeling away, so I returned them and got a slightly better made pair, but I can't imagine them lasting all that long. The cleats aren't inset very much either, so they're like wearing tap dancing shoes.
The pedals are great though. They look and feel bomb proof, and by all accounts they pretty much are. And because I greased the thread on my other pedals before fitting them, it was a two minute job fitting these. I loosened the clips (both sides of both pedals!) to their loosest settings, put on my shoes, leant up against a wall and tried clipping in and out. Hmm, pretty simple. I went for a ride round the park to practice where not many people would see me falling off, but I didn't need to worry, as it was really easy to clip in and out. However, my feet felt like they were too far forwards, so I went home, moved the cleats back and went out again. Much better. I was surprised by how easy clipping in and out was. Clipping in is much easier than with toe clips; pretty much just step on the pedal and you're done, although sometimes it takes a few goes to get it positioned right. Clipping out is even easier; and since my toe clips were a little on the tight side I was already having to wiggle my foot slightly to get it out of them, so unclipping from SPDs feels reasonably natural. I practised getting my feet on and off the pedals while riding, while stopping, and after doing an emergency stop, and had no problems. I am making sure I think 'unclip' all the time as I ride at the moment though, just to make sure.
I've ridden to and from work for several days now without any problems, and I really like the feel of being clipped in. I don't feel any more efficient, but it's nice being able to pedal fast away from the lights because I don't have to mess with my toe clips — even if I can't get my foot clipped in straight away, I can at least pedal while unclipped without having toe clips hitting the ground. And this morning, as I threaded my bike between parked and stationary cars, I unclipped my left foot and rode carefully between the cars, and I felt much more in control than usual; I'm not sure why, since it shouldn't have made much difference there.
I don't think I'll be going back to toe-clips now, and I'm probably going to get myself some Shimano MT71s to replace the Aldi shoes soon, so that I can walk in the same shoes I ride in.
