I picked up a pair of these for about £20. Royal Navy deck boots, made by T&H Bros., 1992.
Lovely quality, very robust and made to military specifications.
Heel - heavy wooden heel - six layers of leather with a metal tip. Nailed.
Sole - Goodyear welted (I believe) and screwed.
Upper - fine quality cross-hatched black grain leather, probably cowhide
Insole - very heavy leather insole.
Leather lined in places
Traditional work boot style.
True to size. Much...
