Specifications: Gore-Tex and Thinsulate. Likely from the 1980s. Purchased used approximately two years ago and worn once (about 2 hours) on a snowy day. There is no size notation, so measurements are approximate: Outsole length: Approximately 32.5cm (inside is about 30cm) Height: Approximately 27cm Width of the outsole at the instep: Approximately 11.5cm My foot size is 26.5cm, but I was able to wear them without any discomfort by tightening the laces. The soles show very little wear. The rubber parts of the soles, etc., were treated with rubber protectant every six months to prevent deterioration. #LLBean #GoreTex #Thinsulate
