Men's Sperry Cold Bay Duck Boot

3-Eye lace up Thinsulate™ These are a great looking waterproof shoe/Duck Boot that my husband has worn some, but he prefers his tall rubber boots. He said they feel like they run a bit big, maybe a half size. So it sounds like heavier socks can be worn with this shoe. Please see tape measure along bottom of sole for comparison. They still look pretty new, you can view the amount of wear on the bottom of the soles in the pictures. Questions are always welcome.
