These are some of the best BOK's I have owned. I have the lime/blk and not only are they super cool looking they are extremely durable for all types of workouts and wear. You can wear from crossfit or for general gym use. They feel like a version of the Nano's but much cheaper. They are flat but yet yield support for deads, cleans, squats, etc.. Def would recommend to anyone looking for a shoe similar to the Nano but a bit cheaper.
