Perceived support is increased with contoured foot orthoses in cycling shoesBousie, JA., et.al. (2012). Contoured in-shoe foot orthoses increase midfoot plantar contact area when compared with a flat insert during cycling. Journal of Science and Medicine in Sport.
A 12 participant randomised control trial undertaken to look at the influence of contoured foot orthoses on surface contact, pressure and perceived comfort when compared with a flat insole during seated stationary cycling. Although the authors qualify the limitations of this study the results do provide some initial evidence supporting the role of orthoses in cycling when the desired clinical outcome is to influence surface contact, pressure, and perceived support within a cycling shoe. Further study in this area will prove most interesting.
