I bought a size 7 .5 It fits perfectly fine, lovely and is very comfortable for a everyday wear and exercising. Great quality for your money !

For reference, I normally wear a 7 1/2 or 8 in medium width shoes. I thought I'd try a 7 1/2 wide in the Runfalcon as they seem to be a narrower shoe by design. I had a sideways fingers width of space in the shoe. The width was generous for me, possibly considering a 7 due to the generosity of space in the shoe. It's right on the edge of a perfect fit and a little too much space. The design looks sharp and they don't make your feet look huge. Would recommend!
