Structural design steps for trail running shoes are similar to those for running shoes. First draw outline of half-panel, use reference line to find control points for mouth, foot and ankle, and then define main points according to selected set of design options. Create points, connect control lines, and then design large contour lines.
Note position of mouth, which is moved forward 10 mm from general mouth, which promotes flexion of toes.
Based on large contour line design, eye cap, shoe eye position, front cap, brow, back cap, side trim and false line are designed. The door has been raised by 2mm, thickness of rear arch material has been increased by 6mm, and foam at neckline has been increased by 4mm.
After completing design of eye cover, it is necessary to extend midline of front of back, and you will find that ears on both sides of eye cover exceed midline of back, so it cannot be cut directly. In this situation, there are three solutions: first, wiggle treatment to maintain original shape of eyelid; second is to detach eyelid and change shape a little; third is to use a broken eyelid. completely changed.
Because purpose of removing stilts is very clear, that is, not to overlap inside and outside of lugs of shoe and not affect cutting of material, so treatment method is relatively simple: redefine posterior midline of eyelid.
First raise height of foot 2mm to find reference point a, then find second reference point b at middle of anterior eyelid width, connect two reference points to change midline of back of eyelid. eyelid, and then it can solve cutting problem. There will be slight changes to front of eye cover, and generally it will not affect operation of upper sewing and effect of finished shoe.
