Pain & Numbness

Medical explanation
pain and numbness in the foot

If nerves or blood vessels are constricted due to pressure, the blood circulation is reduced, or the nerve fibres are irritated which results in numbness, paresthesia or even pain in foot or toes.

Causes of numbness and pain  

One-sided foot load 

Cause - One-sided load   

Pedals with short axis usually allow only a parallel foot position

SQlab Solution 

Pedals with different axis lengths for a natural foot position

Standard pedals force the feet into a nearly parallel position. The extended axis of SQlab pedals allows a more physiologically natural foot position. This prevents strain predominantly on one side – especially in terms of shin splints.

High pressure on the foot 

Cause - too much pressure on the foot 

expresses itself in the form of numbness and pain 

SQlab Solution 

insoles adapted to the foot type

The results of pressure mapping show the magnitude of pressure beginning with blue (less pressure) to green/yellow/orange/red (high pressure).

Too much movement, or incorrect placement of the foot, causes a high pressure to the vessels and nerve tracts through the middle foot. Even with a normal foot position, muscle fatigue can cause a sagging of the foot arch and hence lead to problems. Muscle weakness: daily walking in shoes shortens and weakens the long and short foot muscle groups.

Corresponding to the various foot types and specific requirements in cycling, we have developed insoles that support the various different weaknesses.

Benefits and function of the insoles: 

  • optimal pressure distribution
  • maximised power transmission
  • support for the foot arches
  • relief of overstressed nerves

High Arch

The strongly pronounced longitudinal arch requires a high bearing surface to prevent it from sinking inwards.

Medium Arch

The normal lowering of the longitudinal arch is counteracted, the foot is only supported in its position.  

Low Arch 

The less pronounced longitudinal arch is only slightly supported.

Flat Arch 


The slightly pronounced longitudinal arch requires only minimal support to avoid pressure points.
