Crossfit currently has the 4.0 version of their “Nano’s” workout shoes, made by Reebok. I picked up the 3.0 version of these a couple of years ago and loved them. I still have them and still use them. The shoes have less of a lift to the back heel and more of a flat stance. I’ve found this to be most helpful when improving the weight I can lift and my balance. If you’re looking for a good workout shoe I’d recommend giving the Nano’s a look.
I’ve had good experiences with Reebok athletic gear and clothing, not only on Crossfit gear and apparel. I’ve also been able to find good stuff at good prices by checking out Reebok’s Outlet section of their website, which often hosts bigger sales and discounts and items that a still great quality, just may not be brand new.
