skates

Skates are devices worn on the feet to enable gliding on a surface. They can be broadly categorized into ice skates, roller skates, and inline skates. Ice skates use a metal blade fixed to a leather or synthetic boot; roller skates use four wheels mounted under a boot; inline skates have wheels arranged in a single line.

Historically, ice skating originated in northern Europe and Russia with blades made from bone or wood. The modern metal blade appeared in the 19th century, improving edge control and speed. Roller skates with four wheels in a square configuration date to the 19th and early 20th centuries, while inline skating gained popularity in the 1980s and 1990s with lightweight wheels and bearing improvements.

Common skate types include figure skates, which have toe picks for jumping and, in some models, a longer blade; hockey skates, which prioritize protection and maneuverability; and speed skates, designed for high velocity. On roller skates, quad configurations (two wheels in front and two in back) contrast with inline skates (wheels in a single line). Boots, frames, blades, and bearings vary by use.

Care and safety: proper fit is essential; protective gear such as a helmet, wrist guards, knee and elbow pads reduces injury risk. Skates require maintenance: ice blades may be sharpened; roller and inline bearings need cleaning and lubrication, and wheels or blades should be replaced as worn. Skating is practiced recreationally and competitively around the world, in arenas, rinks, streets, and tracks.
