Last: 12508 Width fitting: F Fully leather lined with full leather insole. Goodyear welted Dainite studded rubber sole and heel. Hand crafted in Northamptonshire, ENGLAND The latest in a line of Cheaney's Vintage collection is Jarrow, our Men's Derby boot in Black Chromexcel leather. Goodyear welted for durability and finished with a Dainite studded rubber sole for superior comfort, Jarrow is an industrial-esque, rugged boot that's made to last. Chromexcel leather is a combination tanned leather that undergoes at least 89 separate production processes and takes 28 working days to complete. Chromexcel is the classic "pull-up" leather meaning that, when folded and flexed, greases and oils that were infused into the original hide migrate, causing a very nice tonal effect. The leather also develops a 'refined ruggedness,' a character of the leather whereby creases and furrows will quickly appear through the material, giving the boots a worn-in, vintage aesthetic.
