Athletic shoe soles

key to speed and traction

What is the sole of athletics shoes?

The outsole is the part of the shoe that makes contact with the ground. It is designed to provide maximum grip, lightness and an immediate response with every step. In athletics, the outsole is crucial for transferring the power of running with no loss, ensuring stable and secure footing - especially on tartan or synthetic surfaces.

Technical characteristics of the sole in running shoes

  • 1. Ultra-lightweight materials
      • The sole is typically made of a high-strength yet lightweight rubber to minimise the shoe's overall weight.

      • Some soles combine rigid and flexible materials to enhance performance in different disciplines, such as speed, middle-distance and long-distance running.

  • 2. Spikes

      • They are the most distinctive feature of athletic shoes.
      • The spikes provide maximum grip on the track, preventing slippage during starts, turns and explosive movements.
      • They are strategically placed in the forefoot and forefoot of the sole to optimise traction without compromising on lightness.
      • The length and type of stud vary according to the discipline and type of track.

  • 3. Minimalist design

      • The sole is typically thin and rigid to ensure direct, lossless energy transfer.
      • There is often little cushioning, as the aim is to maximise efficiency and responsiveness.
      • Often, a stiff or carbon plate is integrated into the sole to increase propulsion.

  • 4. Support areas

      • They are designed to optimally distribute weight and force, adapting to the athlete's specific stride.
      • For sprinting, the support area is positioned further forward to favour the metatarsal stride.
      • For middle and long-distance running, a balance between support and comfort is required for endurance.

Which sole is better according to your speciality?

Discipline. Ideal sole characteristics. Speed (100m, 200m, 400m). Ultra-lightweight sole, short, stiff lugs, minimalist design. Mid-distance (800m, 1500m) Sole with medium spikes, a little more flexibility and stability. Long distance and long distance Outsole with shorter or interchangeable lugs, more durability and comfort.

Benefits of a well-designed sole in athletics

    • Provides maximum grip for an explosive start and acceleration.
    • Extreme lightness improves speed.
    • Energy is transferred efficiently from the foot to the ground.
    • Provides stability and control when cornering and changing pace.
