1. Shoe Flex Tester

• Utilizes the MTS Servo-Hydraulic testing machine.
• Evaluates the stiffness, flexibility and responsiveness of the shoe sole and forefoot in flexion.
• Flexes shoes to 55 degree flexion angle.
• Data collected includes: force, moment, stiffness, input energy, and output energy.
• This information is used to measure the flexural characteristics of the shoe in relation to the biomechanical response of the foot.

2. ASTM Type A Impact Machine

• Simulates 150lb. man jogging by dropping an 8.5 kg mass from a height of 50 mm.
• Data collected includes: force, displacement, time-to-peak force, dwell time, stiffness of shoe, acceleration, input energy, and output energy.
• Measures the resiliency and shock dispersing qualities of shoe sole systems.
• This information is used to categorize shoes for shock absorption, stability, and general comfort.
