The Heston cleverly marries a very sturdy sole unit with a sleeker profile. However, this is not an overly slim shoe and is thus able to breathe new life into the classic Brogue shoe and boot uppers in a way that looks - and feels - very natural. Topped off in polished Wyoming leather, this is an ingenious and beautifully executed collection. * The upper and sole are sewn together, not merely glued, like many footwear constructions. * Products with a plain welt are still stitched, but the constructional thread is not visible. * It is oil- and fat-resistant, tough and offers good abrasion and slip resistance. * A leather with a subtle grain and an oily surface that has been polished.
