I have ordered so many hiking shoes and boots and have returned them almost the next day. If they don't feel comfortable while wearing them around the house for 10-15 minutes, then they will not feel comfortable on long hikes.
This pair I kept. These shoes felt good when I put them on and have felt comfortable ever since. I use them for short walks - 2-3 miles around my neighborhood, but I bought them for a long hiking trip this summer.
My usual size is 7 1/2M and that's what I ordered and they fit great even with thick wool socks. The toe box is roomy and my toes don't feel jammed at the front of the shoes. My heels stay in place. I do have to double knot the laces since they get undone in the middle of my walk if I only use a single knot.
