New. EHS Carbon Short Track boots. The EHS ST boot combines a super supportive advanced composite structure with super strong - light and durable reinforced synthetic leather uppers. Interiors are packed with heat set padding that forms a near custom boot fit feel on most any foot shape. On top of that, the tongue is also fully customizable and easily separates from the boot to allow it to be molded individually. We, were pleasantly surprised by how well they hold the foot and perform for a production boot. So far it is shaping up to become the best performance fit of any production ST boot on the market.
