... you have long second toe.  I wear an 11, and sadly these are too short, several toes hit the end of the toe box.  I have another pair of Merrell barefoots called Spice, they fit great, so too bad on this style.  The shoe was also more difficult to get on, probably due to the shape of my foot, but I couldn't loosen them easily because one set of the laces is permanently stitched down, I guess to keep the shoe fitting as intended (glove-like).  Excellent looking shoe, I had the gray and purple, subtle and low-key, which I really like.  I might look at the men's equivalent shoe for my size and see about trying a pair of those.  Meanwhile, if you're shopping barefoot styles, I suggest looking at the Merrell one called Spice, it's a great casual shoe, seems to run true to size, and looks terrific with slim jeans.  When I got the first pair, I liked them so well, I bought 2 more colors.  I've had good luck with Merrells over the years, I once cured myself of plantar fasciitis by wearing Merrell slip-ons absolutely 100% of the time I was on my feet, and after some weeks, a persistent problem that plagued me for years was gone.
