Comfortable Running Shoes

Compared with the leather shoe last, the sports shoe last has a big difference in shape change. In order to facilitate the movement of the feet, the front and rear sway of the sports shoe last is small, and the change of the concavity of the bottom center is also small, so that the change of the sway curve of the bottom of the last is relatively gentle. In order to improve the foot-accommodating capacity of the shoe cavity, the genetic circumference of the sports shoe last is larger, which makes the shape of the last fuller, and the angle between the front and back of the last body is relatively large. The arc of the heel of the sports shoe last is relatively straight, and the bottom corrugation line of the inner waist is also relatively straight. On the whole, the focus of changes in sports shoe lasts is on the forefoot and the front tip. From the shape of the last, there are mainly four types: pointed head type, round head type, square round head type and square head type.
(1) Round head type Most of them are used for the last design of running training shoes, tennis training shoes and football shoes.
(2) The square head type is generally used for the last shape design of bicycle racing shoes, which is a typical special sports shoe last.
(3) The square head type is generally used for ball sports shoes, such as basketball shoes. Because the front tip is stressed when it hits the ground, the stability requirement is high, and the square round toe sports shoe last is the most used type of sports shoes.
(4) Pointed toe type is generally used for the last shape design of shoes for special track and field competitions, and is not suitable for excessive landing in sports.
The change of the last of the sports shoes determines the head shape of the sports shoes. Generally speaking, unless there is a higher requirement for the force on the front tip of the sports shoes or the direction of movement, the round toe, square toe, and square toe can replace each other.
Compared with leather shoes and rubber shoes, the outsole patterns include delicate two-square continuous and four-square continuous small patterns, rough geometric shapes and free patterns, and light soles without any traces; Wedge soles and mid-heel suspension soles; some sports shoes have nail and rake devices on the soles, and some special sports shoes have functional devices such as pulleys, skates and iron frames on the outsoles. Outsoles of leather shoes seldom use sole fences, while sports shoes fences are quite common, and the fences have various shapes.
