As a fitness professional who teaches multiple classes a day, I'm very picky about training shoes. These shoes do exactly what they claim to do with the lightweight, flexible design. They're very comfortable, which is key with workout shoes. The technology of the flex nodes allow for natural multidirectional movement.
The combination of the lightweight feel, along with the flexible support, is perfect for high-intensity classes and a variety of movement. I've been wearing them for step classes, BOSU classes, HIIT workouts, and even for weight training. They are currently on the top of my list for cross-training shoes, although I did just customize my own design for a new pair of CrossFit Nano 2.0 shoes. I can't wait to get my hands on those.
