The Bauer Supreme M4 hockey skates are designed for the player who skates 2-3+ times per week and is looking for a good balance of fit, performance, and comfort. 3D Lasted Flex Composite Quarter Package LS+ Runner for longer lasting edges 48oz Felt tongue with exposed injected metatarsal guard Standard Symmetrical Flex Facing Thermoformable for a customized fit Form Fit+ footbed with memory foam Over the last couple of years Bauer has been focused on separating the performance attributes of the Supreme and Vapor skates from an on-ice performance and feel perspective. The new technologies, new materials and different flex points are what will differentiate these skates. Supreme focuses on power with the lower part of the skate being stiffer to optimize energy transfer and the upper part of the skate being softer allowing for increased mobility. The Bauer Supreme M4 has a 3D lasted Flex Composite Quarter package which provides great support and thermoforming capabilities. The outsole is made of Digi Composite which allows the skate to maintain its lower stiffness to generate power in every stride. The 48oz Felt tongue with an exposed metatarsal guard provide you with comfort and protection in key areas of the foot. Internally, Bauer uses Aeofoam to provide optimal comfort for the ankle, and a hydrophobic microfiber liner. The footbed had Form Fit+ technology with memory foam to keep your foot locked in place throughout the game. The Supreme M4 skate provides players with great protection and performance features to make this model a terrific value.
