Don't shell out a hundred dollars for a lift ticket only to be miserable all day long due to frozen feet. Instead, pick up the Sidas Neo Set with Custom H Element and carve up the groomers in single-digit temps with happy, toasty feet. This boot warmer runs off of a rechargeable battery that provides constant warmth for up to 6 hours, while the Custom H Element insole has a trimming line on the reverse side to help you dial in just the right fit before you hit the slopes.
