text: This shoe runs small. I have another pair of Altras - but in a different style - that were size 10.5 and they fit perfectly. I have enough room for my toes, even after they have swollen from running many miles. This brand - One2 - is too small at size 10.5. I feel as though I'd have to purchase an 11.5 just to be comfortable. I returned them for a refund.
