Thanks all.
WHat about cleats?
I found my pedals. They are Deore PD-M545s. They seem mechanically similar to 454s that shimano lists on its website, but with metal cages instead of plastic.
According to teh actual Shimano manual,
(link) you can use single direction release or multiple direction release.
It says single release mode cleats are better for jumping because they stay on your feet better. However, if I used the other ones, and I rode them like I ride my flats and didnt just rely on the clip in, would I be safe? What are the real pros and cons of either of these designs? Being someone who has rode flats all my life because I love dirt jumps, I always skipped over whatever I saw relating to clips because it didn't apply to me. So, I know nothing about this. Sorry, and thanks for all your help!
As for shoes, I can't spend too much since I would pretty much need new ones once a year. I was thinking that if they somewhat resembled normal shoes, I could buy them so I could also use them for flats and just everyday walking. That would kind of justify another pair of money-sucking shoes.
