A chunky heel is a thick, solid built heel that normally does not taper much and often resembles a stacked block. Chunky heels are generally more comfortable to wear than other heel types such stilettos and are often chosen for the added support and stability they provide on high heeled footwear. Chunky heels are available in different heights and shapes and can be found on a wide variety of shoe styles.
Platform describes footwear with raised, thick soles of at least one and a half inches in height. Platform soles are often made of cork, plastic, rubber or wood and are generally worn for fashion or to add height.
Slingbacks are a type in shoe in which the heel is exposed yet is contained or secured by a strap that sits above the heel around the ankle.
