Very cool old boots, unfortunately I don’t know who made ’em. Quality on par with any Danner or Red Wing make or model. 7.5 in high shaft. Unique vamp construction minimizes seems. Eyelet and hook lace up. Goodyear lugged soles the America equivalent of Vibram. Lined uppers and thick felted wool insoles suggest they were intended for colder weather use.
UPDATE: Reader comments have identified these as “US Army issue Ski/Mountain boots. The original design is by Chippewa, but several manufacturers produced them over the years. The squared toe and grooved heel are for the ski bindings.”
