  • THE TYPICAL WORKER WALKS UP TO 7.5 MILES A DAY
  • A BUSY HOUSEKEEPER WALKS CLOSE TO 10 MILES (THE

CUMULATIVE IMPACT ON THE FOOT IS SEVERAL HUNDRED TONS)

  • THE AVERAGE PERSON WALKS SOME 70,000 MILES IN A LIFETIME
  • ABOUT 50% OF ALL ADULTS SAY THAT THEIR FEET HURT

Narrow Heel Cushion

  • the heel cushion should not be wider than the body of the heel, this would

increase the moment arm and produce early and excessive pronation Rearfoot / Forefoot Height Consistency

  • a plantarflexed foot will jam the Talo-Crural joint and minimize loading and

energy transfer. It will also exacerbate a valgus hallux Minimal Cushion

  • if the shoe has too much cushion, it will ‘buffer’ the kinetic pulse of GRF and

insufficient energy will be transferred into the body Purposeful

  • does it serve the purpose for which it is designed?
  • consistent with wearer’s physiological state?

Adequate Forefoot Space

  • having a narrow shoe or lacing up the shoe too tightly impedes the navicular,

medial cuneiform and mid-tarsal joint from moving; thus limiting loading of the foot and sub-talar joint.

  • also important to note that inadequate forefoot space will create a valgus hallux

Minimal Stiffness

  • a shoe that is too stiff will impede proper arthrokinematics
