Jade Zip Bootie (Women)

I went to Nordstrom Rack to pick up my shoes today. It is very nice and comfortable. I usually wear a 7 1/2M, but this time I order 7 and 1/2 W, but it is still tight, so I am going to return and order another pair. However, I do not know what size will fit me, 8 W or 8 M? Please help me. Thank you.

These are beautifully made shoes, and after buying my first SAS sneakers which fit perfectly in a 9W, I was looking forward to wearing these in the same size. But they are sized differently: I compared the removable soles of these with those of the SAS Tour Mesh LT sneakers, and they are 3/8" of an inch narrower. So it would need to be wider yet to fit. I might have considered ordering in a wider size, but the toe cap was so low that it pushed down on the top of my toes. I need a roomy toe box, so sadly, I returned.

My feet are thanking me for buying a pair of SAS leather boots with selections of width which is very important to have wearing them with a pair of warm socks in the winter. There's only two color selections but both are easy to match with dark pants/denims/cords in the cold weather. I've heard good things about SAS sneakers being very comfy and that's the main reason I picked a pair of SAS leather boots for the very first time and I can tell I've made an excellent choice to own a pair of boots made in the USA.
