Review on SilentCare Waterproof Men's Hiking Boots: Lightweight, Non-Slip Mid-Rise Outdoor Shoes for Work, Trekking, Mountaineering & Winter Ankle Support by Bill Wasson

If you want to add more warmth to your feet then get at least 1 0r 1 1/2 size over. The boot is not enough to warm your feet below 30. I wear 9.5 and purchase size 11 because I replace the existing orthotics with a better one which add more comfort as I walk. The product and design is decent not bulky or cheap looking material.
