If you are looking for shoe recommendations...
I really like the Mythos shoes, I've seen a lot of people using those and they're really popular, if you are looking for recommendations. Good balance between comfort and toe box, and a lot more comfortable on cracks then most. For a comfortable shoe, you can get a pretty good toe on a ledge and it feels really good to walk around on these or leave them on if you are doing multi-pitch.

I just got a new pair of shoes ($20, it was closeout sort of deal, felt good at the time) and I would say, avoid these ones. (good thing they don't have it at MEC I guess)

I honestly hate them, it feels like a wooden shoe. I've been doing more 10b's then 10d's since I got this shoe just cause I can't get my foot on any sort of small feature, whereas I could on even the cheap evlov shoes (

You must have to have balls of steel to dyno on lead though. I'd probably break an ankle trying to do that.
