How do I know which pair of sneakers to get?

So I have the Zoot Ultra Race 2.0 right now and I absolutely love them. They’re basically perfect. But I’ve only used them to train for a sprint triathlon and some 5k’s. Now I need a new pair.

I’d like to stick with Zoot, but should I get a different model since I’ll be going longer distances? How do I know which pair to get? Here’s their catalog: http://www.zootsports.com/mens/footwear

I’m 6’3’’ 215 lbs. but I feel very light on my feet when I run. Also, I’ve never had any foot problems, but then again, I’ve only trained for short distances.

Thanks.

Info about the 3.0 says:

“The men’s Race 3.0 delivers unmatched comfort and smooth supportive performance for all of your triathlon racing needs. For a similar feel in a neutral high-mileage trainer, the Ultra Kalani is the perfect shoe.”

I’d say they probably know what they’re talking about. Maybe try the Kalani.
