MBT's should fit the foot perfectly.
MBT Shoes don't let your foot slide forward with every step, like normal shoes do, they pull your heel back instead. For this reason, MBT's should never be bought too large. It's alright for the tips of your toes to be almost touching the edge of the shoe.
MBT Ema Sandals will be like no other sandal you've ever worn. While its strappy, topstitch decorated, full-grain leather offers a fashionable look, there's magic happening underfoot: The thick rubber sole has been specially designed to increase the muscle activity required for each step while also ensuring a natural, comfortable rolling motion.
