    Results

    All results of the study: a force increase in every measurement, 58 N on average, range 9 N to 180 N, plus the approximation to the 50/50 distribution.

    The results fall into two findings: an increase in transmitted force and a more even distribution of that force across both body sides.

    Finding 1 — increase in force

    Figure 1. Total force in newtons per measurement, without insole and with the Winsole insole (9 measurements).

    In all 9 pressure analyses an increase in force was measured. The increase averaged 58 N, with a minimum of 9 N and a maximum of 180 N. Not a single measurement showed a reduction in force.

    Finding 2 — symmetry

    Figure 2. Deviation from the optimal 50/50 distribution of pressure moments between right and left foot.

    The optimum is reached when both feet apply an identical amount of force. Without an insole the deviation from this 50/50 distribution averages 7.4 N. With Winsole insoles the deviations are 1 N lower. The study concludes that an approximation to the ideal distribution can be achieved when the insoles are used.

    Observed relationship

    At higher pressure moments the force increase was also greater. The study interprets this as foot and knee joints having to stabilise particularly high pressure and compensate potential instabilities at high power output. This relationship was not conclusively quantified.

    Summary of the study

    Summary
    Alongside a reduction of wear and injury risk, the data of the pressure distribution analyses show measurable effects on power transfer between foot, cycling shoe and pedal through the use of custom insoles by the company Winsole. A loss of performance caused by asymmetric power transfer could be minimised and compensated. In particular, an increase in force was measured in every single measurement when using the Winsole custom insoles.
    Context
    • According to the study the relationship between absolute pressure level and the magnitude of the force increase is plausible, but it could not be conclusively quantified.
    • The study names a dedicated target group analysis as a possible next step of investigation.
    • The document contains no details on the number, age or gender distribution of the individual test participants — it only states that male and female cyclists of different performance classes were measured.
    • The document names neither manufacturer nor model of the pressure measurement system used, and reports no statistical parameters such as significance level or standard deviation.
    • The study contains no statements on watt figures, time savings, race results or medical effects.
