This character wearssandals.

Sandals are an open type of outdoor footwear, consisting of a sole held to the wearer's foot by straps or thongs passing over the instep and generally, but not always, around the ankle.

While the distinction between sandals and other types of footwear can sometimes be blurry (as in the case of huaraches—the woven leather footwear seen in Mexico), the common understanding is that a sandal leaves most or all of the foot exposed.
