I ordered this during the Prime Day and got a great deal for it. Tried it on and the size was just right; sizing is the same as the One 2.5. The wide toe box and cushy mid-sole was great and something which I've been looking for to replace the pointy-toed shoes that every other shoemaker makes. But when I started to walk around in them, the right heel felt loose. When I took off the shoe to inspect it, I realized the collar of the shoe was about half and inch lower on one side. It's clearly a manufacturing defect. I had the shoes replaced, but was disappointed with the quality control of Altra. Otherwise a very comfortable shoe.<br /><br />I just received my second pair to replaced the first pair which I returned. There is some noticeable unevenness in the stitching. I think Altra still needs to iron out the manufacturing process. Their running shoes do not have such quality problems.<br /><br />That said, the shoe is very comfortable! The wide toe box needs some getting used to, but boy it feels good to stretch your toes!
