I US 10.5 E; I ordered 11. The shoes are really tight and the seller is right to ask for a disclaimer. These moccasins are best suited for a narrower foot. A nice addition to my wardrobe for the price. For those not sure if this is what they need, they are affordable enough to try. However, you get what you pay for. The quality is lower than expected. Mocha lovers will have to pay more for higher quality to be satisfied.
