These are tactical boots that will wear and make you happy.

2、 Detailed Structure
（1） Toe cap
The toe of the S4.5 shoe presents a rebellious upward angle, which is full of momentum. On the one hand, it provides us with a larger approach angle, and has a reasonable advantage in the landing sequence of toes, soles, and heels during tactical advancement.

The leather treated with coating on the toe box is more wear-resistant, and it will not leave any marks even when slightly scratched. With just a little maintenance, it can be restored as new;

The toe box contains a hard lining board, which will not deform even when pressed hard, further improving the protective performance of our feet. This design is particularly important when dealing with the impact of dense crowds.

（2） Shoe body
The shoe design can be said to be extremely meticulous, whether it is material or structural design.
In terms of materials, softer leather is used on both sides of the arch and the collar of the shoe, combined with high-strength nylon fabric in the middle, greatly enhancing the wrapping feeling of the shoe body to the foot, and the smaller foreign object feeling brings a more fitting wearing experience.
The nylon fabric covering the outer side of the collar gave me a great surprise. Many tactical boots are made of breathable mesh here, but many tactical pants have Velcro locking and limiting cuffs. The Velcro hook surface can easily scratch the sponge on the outer side of the collar, which can wear out over time and easily leak out. The nylon fabric of S4.5 does not need to worry

The contact surface between the inner side of the collar and the calf is covered with breathable sponge, which is delicate, soft, and does not wear the skin.
In terms of structural design, the integrated vertical support strip formed by hot pressing on the inner and outer skin of the arch can not only enhance lateral support, but also combine with the texture of the arch on the sole to serve as a guide slot for our rope descent, enhancing the tracking effect when the rope slides over.
To improve the strength and fixation ability of the collar position, the collar position of the S4.5 shoe is covered with double-layer leather material, with double stitching and metal eyelets, which is not only durable, but also strong in temperament.

（3） Shoe tongue
The outer layer of the S4.5 tongue is made of nylon fabric, and the middle layer is a flexible sponge with a soft feel. The connection positions on both sides of the tongue are at the height of the second shoe hole, and the contact surface with the top of the heel is consistent. As long as the water level is below this point, the inside of the shoe will not enter water.

（4） Heel system
The heel leather is consistent with the toe, making it more wear-resistant. The heel system with a built-in hard lining board has a very clear fixation effect on our ankles, and it fits perfectly without feeling tight or causing heel displacement. It fits perfectly.

（5） 851 shoe last
The S4.5 adopts the brand new 851 shoe last, which adds a higher level of wrapping to the feet compared to the 850 and is more lightweight. Even if you are a friend with a lower arch height like the author, you will still feel the comprehensive fit. Even if you don't tie the shoelaces, the S4.5 won't kick and pull when you walk.

（6） TERRA FORCE ® Sole platform
The shoe body and sole platform of S4.5 are sewn with front and rear foot stitching, making them more secure; Adhere to the arch position of the foot, even if deformed for a long time, it will not cause cracking at the thread hole position.

3. Vibram ®  Striker ®  Bolt outsole
Vibram ®  Striker ®  The distance between the teeth patterns of Bolt outsole shoes is relatively large, and the height is relatively restrained. Combined with the shape of V-shaped teeth ears, we can know that this outsole is mainly oriented towards all terrain, enhancing the design of climbing ability.
