Ski Boots Atomic Redster TJ 60 - RedSki Boots Atomic Redster TJ 60 Red The Atomic Redster TJ 60 has the race heritage of Atomics top of the line Redster ski boots but made for junior athletes with a smaller build. This boot has the same geometry and fit as the Redster TJ 65 but in a slightly more forgiving 60 flex for lighter athletes. The Junior Performance Shell gives young skiers a progressive flex for better dampening and a supple feel, so lighter skiers can charge with confidence.
