Design Of Front Opening Low Tube Boots

The front opening type short tube boots are formed by extending the notches in the unilateral opening boots and opening and closing functions in place of the zippers.

1. finished product drawing
As shown in Fig. 5-2-8, the front opening position is relatively close, and the saddle shaped surface of the instep is missed. The opening position is connected with three shoelaces and fixed with a Velcro. The front part of the shoe has Baotou, and the side side is not a problem. But the eye cover is a complete part. It can not be directly opened. The position of the broken arm in the design below the first shoelace is very similar to that of the high waist rubber shoes. 2. structure design drawing
As shown in figure 5-2-9, the height of the back of the boot is 150mm and the width of the barrel is llOmm. Because the front opening structure is larger than the opening and closing function of the unilateral open shoe, and is similar to the control data of the ear boot.

Because the opening position is relatively close, it is located in the location of the female shallow mouth shoe door, so we use the counterpoint board to design the front midline of the front part to drop a white one.

There are 3 lines in the opening position. The first line is the instep position line, that is, the position of the instep is determined first. This line is the basis for designing the width of the opening, the length of the shoelace, and the middle line of the tongue. Although it does not directly produce parts, it is absolutely dispensable. The second line is the opening position contour line, and the width is 10 to 12mm based on the instep line. This is not a sports shoe, nor is it designed too wide. This line is also the contour line of the eye cover template, which requires smooth and smooth lines. The third line is the contour line of the eye cover, and the middle position is outstanding, in order to improve the effect of decoration. Although there is no shoe eye position on the lid, the width of the lid should be taken into account.

The shoelace is designed according to the instep line and the material thickness of 3mm is more than that.
The length of the tongue is designed according to the contour of the opening, and its location is equivalent to the position of the eye line.
Other designs are high waist shoes.
