Very nice pair of hard chincup rising! The size 42 as a size 42 1/2 and / or 43. I think this is due to the comfort of the foot swells after long hours of work. By respecting your size I think you will not have the problem of this type of safety footwear ie the shell compresses your toes and it gets painful. The shoe is rigid and a lightness! I advise you not to put a pair of soquette to avoid friction at the ankle but recommends doubling the socks in winter weather. Verdict: REPORT / QUALITY / PRICE at APPOINTMENT ;-)
