FiveTen's, KO's, and OLLO's are commonly recommended. Here's a comparison of the different FiveTen's. http://fiveten.com/community/blog-detail/12341-whats-the Here's a link to the KO's. http://www.knowobstacles.com/Shoe And here's a link to the OLLO's. http://www.ollopk.com/ I trained in some garbage shoes with like...1% grip for the longest time. Just recently switched over to another pair of shoes that have more grip...It was weird training with so much grip, so I ended up intentionally wearing them down. It definitely helped my landing technique, since I didn't depend on the grip of the shoes. Moral of the story: Find anything that feels good for you to train in. Some running shoes tend to have tons of jags and lumps that get in the way of rail precisions, so those can be bad. They're also highly cushioned, which I'm pretty sure results in lazy landing technique. Parkour specific shoes are great, but tend to be a little expensive. I generally like to feel the ground or rails. So any pair of shoes with relatively flat bottoms work just fine.
