The Lethal Tigreor ST 3 Rugby Boot combines revolutionary injury prevention within a cushioned and lightweight frame. It has HG10mm (Heel Gradient of 10mm). This offers the best biomechanical position for running, allowing the foot to work since the body is in a forward position. It also reduces load on the Achilles tendons, calf muscles, ham string and back. Comes with rounded studs for optimum support and traction on soft pitches.
