The Eruption has an Inyati PU/Rubber sole unit, offering high heat resistance, cut and abrasion resistance, and is SRC rated for slip resistance. The upper is made from Buffalo Leather, which is strong and durable. The vamp lining is made from a special needled Hi-Tech Fibre blend, which has excellent perspiration absorbency. This results in a low heat build-up and a more comfortable shoe for the wearer. The quarter lining is from an industrial quality “aerospace sands” type material with good abrasion resistance.
