  1. Selecting the Proper Footwear

  2. Quick Facts • Feet sustain 2 or 3 times your body weight • Each foot has more than 100 muscles, tendons, and ligaments • 6 times force of gravity is exerted on the foot during aerobic activity • 67 million Americans walk to exercise • When rebounding in basketball, 10 times the force of the jumpers body weight during the landing phase • 25,000 heel strikes during a marathon • Body weight of tennis player is magnified 3 to 4 times during start/stops

  3. Components of Shoe Midsole Upper Outsole- Traction, durability, various patterns (e.g.: tire of car) Midsole- shock absorption, cushioning, stability (e.g.: suspension) Upper- secures foot, stability (e.g.: body of the car) Outsole

  4. Outsole Materials • Carbon rubber- synthetic rubber with carbon, used in running shoes • Duralon- soft, synthetic rubber, used in running shoes • Gum rubber-traction for indoor surfaces, used in basketball, cross-training, and volleyball shoes

  5. Outsole Patterns • Waffle-running shoes • Herringbone-court shoes • Hybrid- mix of waffle and herringbone, cross-training • All-trac-mixture of waffle, herringbone, and hybrid, outdoor • *Enhancements (Flex grooves, outriggers)

  6. Midsole Materials • Eva- cheapest material, compressed foam, lightweight • Phylon-responsive, light, molded, contains Eva • PU-durable, stable, heaviest, firm • Phylite-composed of Phylon and rubber, molded, acts as a midsole and outsole

  7. Midsole Features/Enhancements • Footframe • Contoured footbed • Footbridge • Midfoot shank • Dual density Phylon

  8. Things to Rememberwhen purchasing a shoe • Test run • Sport-specific • Individualized • Determine Foot-type • Workout Regime

  9. Just for Thought ……………… What is most important about buying a sport specific shoe? Should we take into account gender when Selecting a shoe?

  10. Just for Thought……. • Prevention of injuries • Performance driven shoe • Gender-specifically designed (weight, structure, cushioning etc) Key: cushioning, stability, surface, distance

  11. Mechanics of Feet oVERPRONATION sUPINATION • Roll of the foot too far inward • Weight on the inside of the foot • Unstable • Flat/low arches • *Pronation-normal motion of foot • Opposite of pronation • Weight on the outside of the foot • Higher arches

  12. Overpronation Supination

  13. Last Mold • Curved Last- will benefit individuals with a high arch (flexibility) • Straight Last- beneficial for individuals with over-pronated feet (stiffness) • Semi-curved Last- flexibility and stability *Activity

  14. Sport Specific Shoes • Aerobics- shock absorption, forefoot cushioning and stability, lateral movement, cross-trainer • Biking/Cycling- really need a shoe engineered for biking but you can pass with a cross-trainer, stiff, rigid outsole, shank • Hiking-uneven ground, need good traction and flexible shoe on forefoot, trail-running shoe • Running-rolling motion of the foot, slightly elevated heel

  15. Sport Specific Shoes • Basketball-lateral movement, pivoting, cutting, start/stops, jumping, hard surface, ankle support, shock absorption • Volleyball- midfoot cushion, responsive shoe, flexible • Walking-cushioning and stability • Tennis-needs to be specifically designed for tennis to allow some sliding, start/stops, lateral movement, soft arch, padded forefoot

  16. Life Expectancy of Athletic Shoes -Replacement of your shoes with wear and tear is imperative -Signs of wear: -worn out outsole -cracks in midsole -diminished elasticity -Ramifications of wearing old worn-out shoes: -back pain -knee pain -foot/ankle pain -Hip pain

  17. Sneaker Retirement • Run: 350-500 miles (4-6 months) • Walk: 500-600 miles ( once a year) • Cardio, weights: 70-90 hrs of exercise • Basketball: every 3 months • Determinants of Sneaker life span -workout (type, frequency, duration, intensity -weight

  18. Featured Shoes…. • Nike Free (3.0, 5.0, 7.0) • Equalon • Pegasus • 360/180 • Walker • Shox • Impax • Basketball/volleyball • Vapor • Alvord

  19. AIR • Encapsulated Air- least expensive, absorbs impact • Visible Air- pressure distributed around heel • Blow Molded-more complex, highest air volume, sport specific • Zoom Air-thin, responsive • Tuned Air-highest air volume, sport specific, specific to body weight, low air pressure • Tube Air-softer, consistent cushioning over a broader base, stability
