In my personal opinion, Mizuno is top-of-the-line in all baseball (and volleyball) products. I recently purchased my coaching/training shoes from Mizuno. If it adds any credibility to my post, I work at a sporting goods store and also coach baseball. I will always depend on Mizuno for baseball products. Of course as always, it comes down to personal preference. Outside of baseball, I'm an Adidas guy.
Mizuno Speed Trainer

The one thing I noticed about the Speed Trainer shoes while looking through the catalog at work was that, in its description, is described as "lightweight" where in fact it weighs 15oz. and is the heaviest shoe in their catalog, including all cleated, molded, and training shoes. I really enjoy my pair, though, and would recommend them to anyone. However, I would recommend also that you get fitted before you buy them. I have always worn anywhere between a 10.5 and 11.5 depending on the brand and type of shoe, but my Mizuno Speed Trainers are size 10 and fit very well.
