If you're doing a lot of hiking, go with the Schnee's pacs. If you're stand hunting, go with the insulated rubber boots. If you want just one pair of boots for both, you could consider the Schnee's and a pair of boot blankets.
Both of my Schnee's boots fit true to size. I would just call them if you're concerned about it, their customer service has been great in my experience.How is the fit on the Schnees? Are they sized assuming you’ll wear some slightly heavier socks?
