Roces ski boots are the perfect choice for your child whose foot is still growing (that's probably the majority of them.) IDEA is the first ski boot growing with the kids. Through the patent pending '6in1' technology, it is possible to adjust the size of the ski boot to accommodate the natural growth of the kids' foot. There are two main advantages to getting Roces boots for your junior skier. The first is obvious in that you don't have to constantly buy new boots to get a great fit. Often overlooked is that since you are not getting new boots, you don't need to remount bindings as your child's foot grows, since the sole length of the boot remains the same as you expand and contract the fit.
