It’s hard to find high-performance boots for preschool- to elementary-age children because they simply don’t come in small enough sizes. Enter the RS J 50: It has a clean, simple classic Lange design, but it comes in a pint-sized 17.5 mm (in a size run up to 21.5 mm) and a child-friendly 50 flex. Design specs include three buckles, a control team liner and replaceable soles. The RS J 50 comes in a big-kid speed blue, but girls might like the Starlett 50—which is the same model but with a white and pink-accented shell and butterfly decals. The last size for this boot is based on a junior width.
