I am new to Vibram Five Fingers style and yet these are the second pair for me in as many weeks because while I love my first pair they are really more for inside and are not as slip resistant on wet rocks going downhill in the woods. I am normally a 36 and originally bought that size. It was only after ordering that I saw on the Vibram website that they suggest going up a size in this style. The smaller size arrived and I struggled mightily and barely managed after minutes on each foot to get them on, but the toe length was not long enough and my arthritic hips make the struggle not fun. So I sent them back and ordered 37s and I am glad I did.  I can get the heel to slide on without a lot of grief and I don't think they will stretch out too much in the wearing. It was raining outside when I put them on so I tested them up the hill in the woods and hit every smooth wet rock and found the grip to be good and the sole to still have good feel of the ground.

For thirty-five years I have had a fourth toe that I broke and strapped to the one next causing it to heal in a bent position, slightly under its neigbour, so I am finding the individual toe pockets to feel fabulous. For me this is better than barefoot.
