...and everywhere else for that matter. The absolute lightest and most flexible shoe you will ever work out in, yet still durable and supportive in the right places! The toebox is streamlined yet roomy, too. I am a personal trainer and multi-seasonal athlete; do strength training, stability, cardio, plyometrics, and crossfit 6 days a week in these babies. After my own workouts they're still comfy enough to keep on while I'm training others. Have them in 6 colors to stay fashionable, PLUS duplicate pairs to wear as everyday kicks outside the gym. Always get loooads of compliments from men and women alike.
Note: I wouldn't run long distance in them (check out the Free Run model), and I am pigeon toed with a supination n slightly high arches, but they work for flat-footers too. GET THESE SHOES.
