    Four Tips For Sports Boys To Buy Basketball Shoes

    The design of modern basketball shoes has special design according to different offensive and defensive positions. It mainly emphasizes lightweight, good grip, strong maneuverability and shockproof function, and has good protection function. Based on the above functions, the following four characteristics can be identified from the viewpoint of biomechanics.


    I. shockproof function


    Shock absorption (Cushioning) can be divided into 2 types: structural and material. Structure such as honeycomb structure and arch structure (Arch). Materials such as air cushion (Air) and shock absorbing adhesive (Gel). The shock-absorbing ability of sneakers is defined by ASTM as follows: "the ability to reduce the impact force peak by the increase of external force time", whether material testing or human body testing, is the impact force peak (peak) or negative acceleration peak (peak acceleration) of vertical ground reaction force. As an indicator of evaluation, the peak value of impact force or the peak value of negative acceleration are small, so the sneakers have a better shock absorbing function and can reduce the incidence of lower limb injuries.


    For example, the classic Weapon Evo, the core technology FEEL brings people more stable and implicit shock absorption rather than stepping on the clouds. Due to the use of the star shock absorber unit, the midsole does not exaggerate the distance from the ground.


    Two. Stabilizing effect


    The upper part of basketball shoes has the function of stabilizing the foot to protect the ankle joint, avoiding the inside and outside of the foot, protecting the foot back, fixing the foot and protecting the Achilles tendon.


    For example, the space style Drop Step has a comfortable bottom shock proof design, an excellent ankle protection sponge, and a breathable hole at both ends of the shoe is designed beautifully and practically. The leather guardrail at the heel of the shoe makes the feet safer in movement and will not fall off from the tongue.


    Three. Anti slip Effect


    The antiskid effect of basketball soles is also a friction function (Friction). Most of the basketball venues in China belong to three kinds of concrete, board and PU. The research results show that the highest ability of shock absorbing is wood, and the highest rebound ability is concrete. In friction, the front friction force is the largest PU material, and the latter is the largest concrete. Front friction is the friction force that shoes pull forward; it is the power to help the human body perform the emergency stop action on the floor. The rear friction force is the Pu city shoe industry, the surface of the site helps the human body move forward.


    The key is the thickness and depth of the shading. Using the deformation of sole texture can increase the friction force between the sole and the contact surface, which can effectively improve the slippage effect of the sole. The large area of herringbone is still the symbol of the most powerful grip of shoes.


    Four. energy rebound


    It's called elasticity. There are 2 main functional tests for sneakers.


    (1) material testing (material test): put the sports shoes on the measuring board or the ground, and test the shoes themselves.


    (2) subject test: subjects wearing Gym shoes They are tested in various ways of walking (walking, running, vertical jumping). The results of vertical jump test showed that barefoot and wearing sports shoes had no difference in jumping height. Showing that the elasticity of sports shoes for jumping is of no real help. The reason may be that the vertical jump of the human body is an active rebound, and if the time of the rebound of the shoe sole can not match the ground action of the body when it takes off, it will lose its function.
