Onex Full Calf Boots Size 8

I purchased these several years ago in a size 8 based on the fact that this shoe brand runs small and you should purchase one size bigger than what you typically wear. This is not true in the case of these boots. I believe they are a true size 8 as they are too big for me and I wear a 7. All my other Onex shoes are size 8 and fit perfectly. These have never been worn, but may be dusty from being in a storage bin. Made entirely of synthetic material. No box.
