(Received 14 September 2014; accepted 13 January 2015) Purpose: Dual density midsole constructions at the lateral rearfoot and medial midfoot provide opportunities to improve cushioning and stability of running shoes. By similar mechanisms, non-uniform midsole density across the medio-lateral direction at the midfoot to forefoot may allow better negotiation of different loading magnitudes of the medial and lateral midfoot to forefoot during running. Thus, the effect of segmented midsole hardness at the midfoot to forefoot of running shoes on perception and biomechanics was examined. Methods: Four custom-made running shoes featured a three section longitudinal hardness pattern at midfoot to forefoot. The central section as well as the rearfoot section always had consistent medium hardness, whereas medial and lateral sections were systematically softer or harder. A sample of 24 runners participated in visual analogue scale based perception measurements and in recording of in-shoe plantar pressures, ground reaction forces, and multi-segment foot kinematics. Shoe effects were analysed by repeated measures analyses of variance (ANOVA) (pVHMVS
