Q: Great boot. Seems like it ran large. I usually wear a size 9 athletic shoe and sandal but this 9 swallowed my foot whole. Maybe it's becasue my foot is a bit narrow. No trouble returning and swapping for an 8 1/2. Solestruck is an excellent company to deal with. Great customer service!!I love these boots!

Positive
