The blades of modern advanced speed skating knives are mostly made of high-quality high-carbon steel, and other parts are made of light alloy. The characteristics of speed skating knife are: the blade is higher than the pattern knife and lower than the ice hockey knife, the blade is longer than these two knives, the blade is thinner and lighter than these two knives (the thickness is 1 ~ 1.3 mm), the blade is flat, and the contact distance with the ice surface is long, which can keep the good linearity of skating. Speed skating skates are made of high-quality thick cowhide, slender, half-high-waisted, and fixed heels surrounded by hard heels. The sole is hard leather, and the roller skates are fixed on the sole with screws or rivets.

The matching length between skates and skates of average athletes is 8-9 cm from toe to toe and 5-6 cm from heel to heel. Because the blades of the two knives are used differently in running, and the body leans to the left when running in a curve, the fixed positions of the two-legged skates and shoes are also different. Generally, the tip of the right-foot skates is installed just below the big toe of the right foot, and the heel of the skates is located in the middle of the heel. The skater for the left foot puts the tip of the skater between the big toe and the second toe of the left foot, and the heel of the skater is in the middle of the heel. The clothes of speed skaters should be warm and light. Speed skaters' competition clothes are all nylon tight-fitting sportswear and jumpsuits. The jumpsuit is a combination of hat, coat, trousers and socks, which is light, tight, low resistance and flexible.
