Runalytics analyzes the relative movement in the space (3D) of the leg and the hindfoot body segments. This movement is processed by a mathematical algorithm based on the analysis of the running pattern of hundreds of runners -performed by experts in biomechanics- and finally recommends a type of footwear, depending on his/her running pattern.

Runalytics is the only system in the market that meets the following requirements:

• It is developed under a mathematical algorithm which analyzes the pattern of the user according to studies of experts in biomechanics, offering results with a classification percentage over 95% of accuracy.
• It is based on 3D measures of the leg and the foot movements. Most of the existent systems in the market are based on 2D measures, so they cannot be so accurate. This makes Runalytics much more reliable than any other product in the market.
It uses only one camera, minimizing the equipment required to be installed on the store, and increasing its usability and robustness (less sources of error). It is possible to purchase a second camera to analyze the two legs at the same time.
• Both the interface and the results have been designed specifically thinking in the needs of the sports stores.

Runalytics is a 3D expert analysis system of the running pattern that enables, with a simple 5 minutes test to classify a runner as over-pronator (slight or severe), neutral and underpronator (supinator), depending on his/her running pattern. This analysis helps to recommend a specific footwear depending on the running pattern of the user with a percentage of accuracy over 95%.

Hiperpronación (también conocida simplemente como pronación)

Pronation is a complex physiological movement produced in a joint located under the ankle (subtalar). This movement describes a rotation towards the internal side of the foot, just after the initial contact between the foot and the ground while running.

As we walk or run, pronation helps to cushion the impact of the initial contact, as well as it helps the foot to recognise the ground and to adapt us to its irregularities. Without pronation, the impact in every step would be transmitted to the upper part of the legs and would affect the natural body mechanics.

The problem arises when pronation exceeds the normal values, and causes an excess of movement, called overpronation (slight, moderate, serious), in which all these functions get lost, and the structures of the foot undergo -tissue stress- which results in common injuries such as plantar fasciitis, sprains, tendinopathies, etc. Statistically this problem is very common, suffered by 40 to 80% of assiduous runners.

Currently, running shoes are specifically designed for different types and degrees of footstep. Therefore, the type of footstep and, in this case, pronation level, are very important factors in the footwear choice. We can find footwear for slight pronation and moderate to serious pronation. The best way to find out how is your footstep is to consult an expert, who will analyse it and recommend you the best running trainers, according to your weight, activity level and training surface.

Supination (or underpronation)

Supination happens when the pronation movement is not performed within normal values. Statistically, it is the most unusual footstep type in runners, only between a 5 to 10% of runners has this type of footstep.

Usually, at the initian contact of the foot with the ground, the external area of the footwear hits the ground with a bigger angle causing a big impact transmission through the lower body. This lateral loading of the foot extends during the whole stance phase, affecting the running efficiency.

For this reason, supinators usually wear out the running shoes on the external part of the heel, and the upper part of the trainer can be misfit, and even deformed, towars the outer side. Supinators tend to suffer injuries such as stress fractures mainly due to the excess of impact they undergo.

If you are a supinator you should choose neutral running trainers, or trainers for supinators, with good shock absorption and avoid double-density half soles. This will help to reduce the impact suffered by the legs and the back while running.

Neutral foot strike (or neutral line-up)


A neutral foot strike would match with the ideal model of footstep. Statistically, only between 15 and 20% of runners have this kind of footstep.

You have a neutral footstep if the wearing out of the trainer sole makes an S shape, that is to say, an initial wearing out in the external side of the heel, making an S shape until the big toe. When you have a neutral footstep you can use a wide range of running shoes. In this case, you should choose the most suitable ones according to your weight, required pressure absorption, running pattern, training surface and usual running distance.
