This is an initial impression. I  using these primarily for MMA work -mainly boxing/kickboxing training. I like the design pattern on the soles which should help with pivots and  turns. The shoes are extremely light weight - probably too light weight - which if I did only grappling/wrestling on mats would be great. However they are so light weight and thin I worry about their durability for heavy boxing training on concrete. I pulled out the glued in wafer thin inserts and added Superfeet carbon insoles to add some notable comfort. The tongue is very large. I replaced the laces with lace-less silicone ties to make them to slip on and off.  I wish there was something like this shoe but made with leather and a thicker base/insole.  They will do I guess for a while, better than running shoes for boxing training.
