I understand fit as the ability of the shoe to wrap and contain the foot properly.
When you start running trail running, you tend to think that trail shoes should fit the foot a lot. Well there's no reason for it to be that way.
- What is the best fit for a trail running shoe and products
The fit, or fit, of the trail running shoe is mainly determined by 4 factors:
- The upper
- The cords
- The back, specifically the heel counter
- The internal space. The last of the trail shoe
It is important to have a good fit of the foot when we want to face fast and technical routes, because the shoes have to be like perfect surgical instruments that allow us to support the foot with precision, without errors.
The shoe must be an integral part of the foot and in this case the foot cannot move inside.
The adjustment must be adequate when, in addition to technical routes, the path presents a lot of unevenness , whether it is a positive or negative unevenness, since the foot tends to slide forward (on descents) or backwards (on ascents) with the consequent inconvenience.
Typically, the toes are crushed on the front of the shoe or blisters appear when the heel rubs against the rear heel of the shoe.
And let's not forget the lateral support, necessary when "tilting" a mountain.
As always, generalizing, we can say that the fit is not very determined by the type of runner and does not depend much on the weight or the trail runner's technique.
In the case of restraint, it will be mainly the route that will decide if a good fit and containment of the foot is essential or not .
