【REDWING PT91 2268 Print Tag】 【Size】US7.5D This is a very valuable pair of Engineer Boots with the PT91 print tag, manufactured in the 1990s. The leather from this era is known as "tea core" leather, where the core isn't dyed through. This pair has been customized at a well-known shop in Tokyo. ⚫︎ Vibram 705 Brown, 5mm midsole ⚫︎ Shaft reinforced with triangular stitching I think this is a chance to get a perfect tea core pair, and a shiny one at that, rather than buying a pair that's covered in scratches and has cracked piping around the opening, even if it has tea core leather showing.
