I was wondering the same, the busnetiz are too thin and the weird heel block trips me up
for me, i am an 11.5 and even with how thick the sole may look, your foot sits deeper into the sole than you would think (makes for good board feel out of the box especially for a cupsole), and the forefront of the shoe is wider than i thought it would be. I have wide feet where my little toe would usually be pinched in most shoes but these fit it perfect with no discomfort. and your foot feels really locked in and comfortable, and the inside of the collar is lined with what I could only compare to a velvet-like softness to slide your foot in and out of without having to force it, if you only tie your shoes once. and the tongue has gel inside of it so you dont get the annoying feeling of your shoe pressing against the top of your foot and being uncomfortable. and the vamp of the shoe is lenient if you need the room, but pulling the bottom laces tight can reduce it if you want a snug fit.
sorry for a long review, but I really love this shoe and for anyone considering trying them, theyre worth it.
