Wirelessly controlled and heated insoles exceed the hopes of hunters wishing for something to keep their feet warm. Thin and comfortable as an orthotic, they’re powered by rechargeable, long-life batteries. Remote control allows users to dial heat up or down to match activity levels, and the new insoles boast Bluetooth wireless operation that syncs with iOS and Android devices loaded with the company’s easy-to-use app. Price: $199.
