When one starts experiencing cold toes and feet while hunting, it might be due to your hunting boots or socks being too tight. In this case, your blood supply might get restricted, keeping your feet from getting warm. To avoid this, make sure your shoes and socks are a comfortable fit - neither too tight nor too loose. Lace shoes can help you regulate the tightness better too. Also, make sure to keep your hunting boots and socks dry, especially so in winter time.
