Nordica GP TJ Super Boot - Youth The Nordica GP TJ Super Boot is a front-entry boot designed for kids with larger feet, with a foot-size range of 23 to 26.5. These boots have shorter cuffs and a softer flex than adult boots making it easier for kids to initiate turns and stand correctly in their boots while skiing. Kids can walk easily up to the ski lift and through the parking lot, because these boots have been constructed with extra traction.
