Type of terrain: Road or Trail
The first element to take into account is the terrain on which you will mainly operate, namely, Running on roads or Trail running on trails , because the constraints are not the same.
The practice of running on Road requires greater cushioning because impacts on asphalt are much more traumatic for muscles, tendons and joints.
For the Trail , priority is obviously given to grip with notched soles, as well as support for the foot and ankle , in order to guarantee traction and stability. The design is also more robust to provide the necessary resistance to abrasion and impact, especially with stones.
It should be noted that there are also mixed shoes , ideal for runners who like to alternate outings on asphalt and smooth natural terrain, and who do not wish to have multiple pairs of shoes. An especially interesting solution for recreational runners.
