I was pleasantly surprised to find that these half height rain boots fit really nicely. Being that I have really large calves, I was skeptical about placing an order. But I find them to be very roomy in the calf area, very easy to get on and off. And also, these boots come up a little higher than most mid calf rain boots.Although, they run quite large. I ordered an 11, I had to send them back and change them out for a 10. The 10 still fits just a tad bit big, but I'm sure a pair of really thick socks will fix that issue. I would advise anyone that's considering purchasing these boots to order a size smaller size than what you would normally wear. These boots are worth every penny.
