I bought these rain boots for wearing while kayaking so that my feet won't get wet when I get in and out of the kayak. The color I bought is green which is a very dark forest green shade. They come with a spare pair of laces in dark green. I normally wear a size 6 or 6 1/2 in shoes and the size 36 (EUR) in these fit great with enough room for wearing thick socks. I have very skinny "chicken legs" (12.5" at the widest point) so I have enough room to tuck in my flare leg jeans. If you have wide calves you may only be able to tuck in straight leg jeans or leggings. The top width measures 16" around. I debated whether to buy these or a different brand that wasn't as wide and I'm glad I went with these. I'm very pleased with my purchase and am looking forward to wearing these kayaking and on the many rainy days we have here in the Pacific Northwest.
