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 (though it is possible without them as well), short trousers and a shirt.
First seen in Europe and America in the early 1900s, T-bars became very common among children in the 1950s,[1] particularly among boys where they supplanted pre-war Mary Janes. T-bar wearing declined after the 1960s nonetheless, following the cultural and clothing revolution that swept the West.
Today, T-bars are more associated with girls, particularly the more classic styles and are often considered semi-formal shoes, appropriate for school (some primary schools in the United Kingdom require that pupils wear them with their uniform[2]). They may also be viewed as formal shoes for children, suitable for religious ceremonies, weddings, visits, and birthday parties for example.
More modern styles are worn in casual settings, however: playgrounds, shopping centres, etc. Although less popular than in the past, T-bars remain a timeless classic of children's fashion and, for many people, a symbol of childhood.
