These Hunter winter boots were purchased a year ago. I think they're in good condition, but as you can see in the photos, there's some pilling inside. Those who are concerned about this may find them unsuitable. Quoted from the website below: The Intrepid Snow Boots are perfect for extremely cold climates. These handcrafted boots feature a recycled nylon upper, recycled fleece lining, and innovative Ortholite insole for a comfortable fit and high performance, allowing you to brave freezing temperatures. 100% waterproof thanks to a water-resistant shell and an inner waterproof film, and the drawstring-like elastic opening and fastener provide maximum heat retention. The outsole is made of FSC®-certified natural rubber sourced from forests independently audited according to Forest Stewardship Council® standards, allowing these boots to be worn even in temperatures as low as -20°C (-4°F). 【Materials】 - Upper: 50% Recycled Nylon, 50% Polyurethane - Lining: 100% Recycled Polyester - Insole: 100% Polyester - Outsole: 100% FSC Rubber
