| Today we use fabrics that are light and stable structures to help our every day runner. Such things as rubber and foam materials are used in the soles of the shoe to give it cushion and a firm base to protect the runners feet. A variteys of plastics that form around the shoe to give support for your ankles and aline you your feet to protect from knee injuries. |

| The diagram above shows foot imprints of Overpronators, Neutral, and Underpronator. Today's shoes are design to the runner foot. If you have overpronation then you can get a shoe that has more support on the inside of your foot to keep it straight. |
| To protect your feet you should get new shoes every 400 to 500 miles. |

| Abzorb: Provides maximum shock absorbency while resisting compression set. C-Cap: EVA molded under pressure provides a firm, cushioned midsole that is lightweight. Encap: A cushioning core of EVA is encapsulated within a shell of polyurethane which adds stability and disperses shock. External Counter Reinforcer: A bracket that stablizes your heel, reinforces the shoe's heel counter and also helps prevent your foot from rolling over. Graphite Rollbar: A lightweight flat or molded piece of graphite material biomechanically positioned in the midsole to maximize rearfoot stability. Board Lasted: Board lasted shoes have a stury insole board running the entire lenght of the foot bed. This type of construction provides the greatest stability. Combi-Lasted: Combi-lasted shoes employ slip lasting in the forefoot for enhanced flexibility and an insole board in the rearfoot to control excess motion. Strobel Lasted: Strobel Lasted shoes are constructed with a thin material action like a sock liner stitched along its perimeter. This construction probides an excellent blend of stability and flexibility. Slip Lasted: Slip lasted shoes are constructed without an insole board. This provides the greatest flexibiliity and lightest weight. Medial Post: A medial wedge of higher than normal density C-Cap midsole material extending from the heel to the first metatarsal head which provides pronation control. N-ergy S.C. System: A blow molded cartridge made of highly resilient DuPont Hytrel thermoplastic, the N-ergy delivers exceptional support and cushioning, heel-strike after heel-strike. By compressing upon impact, N-ergy absorbs shock, providing enhanced comfort for the long run. The high degree of supportive cushioning comes from the two-chambered structure: The stabilixing outer rim provides motion control and support, and the ellipticcal center provides responsive cushioning. Stability Web: A lightweight plastic web made of thermoplastic urethane (TPU) and positioned under the arch, Sability Web allows for torsion and flexion control in the arch while maintaining flexibility. SL-1: A straight last used in many of the New Balance running shoes. Built for the people with a tyrical forefoot and toe box depth, it provides a comfortable and snug fit throught the instep and heel area. SL-2: A straight running last for people with a high arch foot type. It provides a roomy toe box to prevent toe bruising and a slightly wider forefoot than SL-1 last. It accommodates orthotics and has a unique design abd superior fit. T.P.U. Post: A stability device made of thermoplastic urethane placed in the heel of the midsole. If on the midsole side, it aids pronation control. If on the lateral side, it aids in the control of the supination. |
