I have the same problem with many others. I love MBT, but I wish I listend to all these reivews. Normally, I am a 5.5 -6, long toes perhaps, but narrow feet. 6 is other shoes are normally slightly big for me, never small. According to other review suggesting buy two size up, I bought 7 first, then 6.5, heel slips, too big and too uncomfortable. so I got a 6, thinking it would fit. now it is TOO tight. this review gives me hope that I hope my feet sink into it. but so far, my big toe on the right is in pain. I like the shoes and price otherwise. but I am debating if I should return it completely. I end up paing $45 in total for three paris, for returning shipping along. Be very careful, your shipping might add up and it is not worth it. try other style.
