T-bar sandal

Classic T-bar shoes by Start-rite (known as Sonnet in the United States)

A T-bar sandal or T-bar shoe (also known in the United Kingdom as "school sandal" or "closed-toe sandal") is a closed, low-cut shoe with two or more straps forming one or more T shapes (one or more straps across the instep passing through a perpendicular, central strap that extends from the vamp).

Classic T-bars for children are typically made of blue or brown leather, have two thin straps forming a single T shape and fastened with a buckle, a broad and rounded toe box pierced with a pattern of holes, a low heel, and a crêpe rubber outsole stitched-down to the upper. Among boys, T-bars are traditionally worn with socks (sometimes without), short trousers and a shirt.
