Reichswehr period M1866 German Marching Boots (M1866 Marschstiefel). Typical Model 1866 Marching Boots from the World War 1 Period showing the recognizable side-seams. The light brown leather boots are showing size '27' markings and some numbers most likely indicating production in 1932. This is the best pair of M1866 marching boots I've ever seen, mint condition!
