The Primus III is for kids who already know their own minds — and feet. So keep them grounded, but set them free. The updated Primus III has the same ultra-lightweight design and flexible, grippy sole of our bestselling barefoot kids' trainer, made using recycled, animal-free materials. Now engineered with a new tongue construction for a wider opening, letting kids pull these everyday sneakers on and off by themselves. With a toggle fastening for a snug, sporty fit that keeps out the "bits", but lets all the feeling in, making sure feet grip, balance and flex as close to barefoot as possible.
