Ideal for strength training with a stable platform, a little cushion up front and flexible sole, but a dense heel; perfect for compound lifts, machines, box jumps, sled work, stationary bike (with flat pedals.) Enough drop (6mm) and stability for squats, heavy leg or overhead movements. I had been mostly using barefoot shoes (Vivos) for the gym, but prefer these for most of my gym work now. Much better than any runners and much cooler than other stylized gym trainer models, with that classic understated Adidas look. And with the various discounts available, they can be had for a steal. Though if I'm running on the treadmill I'll bring a pair of running shoes to switch into for it; these are definitely not recommended for anything but a very short warm-up or cool-down jog. And I don't do metcon type workouts or classes, but I'd imagine they are suboptimal for those.
