LIKE A NINJA!
Just purchased these to try something other than the MIURA VS' (shits and giggles)
I wear a mens size 10.5 and was able to cram into a mens 7.5 and as much as it is not pleasant these shoes make dime size foot holds feel like no big deal. I haven't had them for a long time and once I break them in fully and destroy them after a few months i will definitely rewrite my review but for now all I can say is.. EDGING POWER!!
Also if your into having one of the uglier shoes in the gym or while outdoors this shoe will definitely facilitate that dream for you. I am not too ecstatic about the Japanese character on the heal but I guess when italians use the name "katana" i guess they feel they should probably stereotype as much as possible...
