2. upper

Large area uses leather or synthetic leather, adding a layer of cloth to improve the strength and flexibility of the upper.

3. Toe

The inside of the toe and toes is strengthened with wear -resistant materials to prevent premature wear and at the same time enhance the stability of exercise.The lining is thick and soft to suck sweat, rich in design, Smooth lines, and the shape reflects professional tennis.

The front and rear wall walls are longer to prevent friction.Complexity, so as to adapt to frequent directions of tennis movements, to meet the requirements of non -slip and abrasion -resistant movements; the thick shock absorbing design after midsole, while improving stability to meet the requirements of more jumping and shock absorption in the movement,Some high -end products are also installed with other special shock absorption materials to reflect more professional sports styles.

1. The technical principle of firestone

Generally manufacture of fire stone alloys, which are widely used in mixed rare earth metals, which are mainly ravioli.Contains light rare earth elements such as , , and .The chemical properties of the rare earth metal are lively, and the affinity of oxygen is strong, while the temperature of the coaching point of the metal of the cricket group is very low ( is 165 C, is 290 , is 270 C), and a lot of calories are released when burning.

2. How to use firestone

Use a metal blade to slowly scrape the stones, producing some dandruff in a small pile of dried grass, leaves, or paper, and quickly planned magnesium strips to produce Mars to cause magnesium to ignite magnesium dandruff.When the flame is generated, add a thin wooden stick to form a flame.
