Adidas Yeezy Kids Foam RNR Carbon Slip On Sneakers Lightweight Unique Clog 10K Unisex Youth 10 I believe these are carbon but could possibly be onyx instead. They are like a charcoal dark gray black. Great preowned condition. See all pictures for details. With a design ahead of its time, the adidas Yeezy Foam Runner Kids gives the low-key clog a noir treatment.

A soft and textured top layer gives the footbed step-in comfort.
