I am experimenting with barefoot training. Doing research. I ordered the Unisex round toe Zem gear. Was not over joyed with those but I think them being unisex made them not fit correctly. Wide through the toe and heel and they are much thinner than what they seem to show pictured. But the SPLIT TOE fit true to size. They look a bit weird, but, I am open to trying them. I will post an update After wearing them (just got them with the round toe zem gear), Both round toe and split toes are strictly indoor use.
