The high performance full-grain waxy Hydro calf leather used for this range provides a good barrier to water, yet remains fully breathable.  Salt lines and most other stains can be wiped off and there will be a high resistance to alkalis and mineral acids so long as the uppers are maintained with a good wax treatment, like Hoggs H-Wax Leather Proofing.  Other features include welted construction with a middle-ply sole (which allows re-soling) plus leather insoles and linings.  All styles are wide fitting and are available in full and half sizes 7 - 12 unless otherwise stated.
