These canvas sneakers are very lightweight and very comfortable. And they look rather good on the foot! Really, a great summer sneaker. That said, I measured my foot and I used the "get your best fit" tool. Both the size guide and the tool said I was a size 10. The 10 arrived, and my foot was absolutely swimming in it. I could fit more than a finger between my heel and the back of the shoe, and the toe box got all scrunched up when I tightened the laces. Turns out, I am a size 9.5 (I even fit into a 9 well, but I like a roomier fit.) I just wish the size guides could have been depended upon, since I missed out on a great sale because of the misleading info.
