When evaluating cotton boots, the upper material should ideally be high-density combed cotton or canvas to ensure breathability and durability. For the lining, prioritize faux shearling, brushed fleece, or 100% natural cotton wadding to provide superior thermal insulation. The outsole must be made of TPR (Thermoplastic Rubber) or Natural Rubber with a deep-lug traction pattern to ensure anti-slip performance on icy or wet surfaces. Additionally, check for reinforced stitching at the welt to prevent sole separation.
