The shoe shall be low cut in style (i.e. below the ankle) with a lace closure system of at least six (6) eyelets on each side. The shoe shall be fully lined and have a removable cushion insert. The shoe shall be built to perform in a range of physical fitness training activities, to include running, obstacle courses, rope climbing, squats, mountain climbers, jumping jacks, and lateral movements on both indoor and outdoor surfaces.

3.4.1 Design types.

3.4.1.1 Type I, (cushion or neutral shoe). The cushion or neutral shoe, Type I, shall be made to accommodate users with high arches and be designed to reduce impact on the lateral edge of the user’s foot. Type I shoes shall be free from medial midsole posts or upper elements designed to limit pronation.

3.4.1.2 Type II, (stability shoe). The stability shoe, Type II, shall be made to accommodate users with moderate arch heights and moderate pronation. This type shall be designed with a medial midsole post which prevents excessive pronation during walking and running.

3.4.1.3 Type III, (motion control shoe). The motion control shoe, Type III, shall be made to accommodate users with low arches and severe over-pronation. This type shall be designed with a medial midsole post which prevents excessive pronation during walking and running as well as elements in the upper to maximize support and control of the foot to prevent pronation.

3.4.2 Shoe weight. The weight of a finished shoe (Men’s size 10 D) with cushion insert shall be less than or equal to 13.5 ounces per shoe, when tested as specified in 4.4.4.

3.5 End item performance requirements.

3.5.1 Shock attenuation and kinematic parameters. Whole shoe shock attenuation shall be optimized for user comfort and injury reduction. The shock attenuation for Type I shall not exceed 15 gravity (G) in the forefoot and shall not exceed 13.5 G in the rearfoot. The shock attenuation for Type II and III shall not exceed 15 G in the forefoot and shall not exceed 15.5 G in the rearfoot. Shock attenuation shall be achieved through the choice of standard materials and construction techniques used in commercial industry and found in this Purchase Description (PD). Human biomechanical gait parameters while wearing shoes shall not be compromised to achieve increased shock attenuation. Testing shall be performed on the completed shoe with the removable cushion insert as specified in 4.4.4.

3.5.2 Bond strength. The bond achieved between the shoe upper, cushion midsole, and outsole shall be resistant to any delamination for the life of the item when tested as specified in 4.4.4.1.

3.5.3 Longitudinal stiffness. The finished shoe shall be designed such that the flex point aligns with the natural flex line of the foot, i.e. at or just behind the ball of the foot. The longitudinal stiffness for the Type I shoe shall be between 3.8 N∙m and 6.2 N∙m. The longitudinal stiffness for the Type II shoe shall be between 4.0 N∙m and 6.7 N∙m. The longitudinal stiffness for the Type III shoe shall be between 4.0 N∙m and 7.0 N∙m. All longitudinal stiffness measures shall be tested in accordance with 4.4.4 and Table VIII.

3.6 Marking, permanent identification. With the exception of Product Demonstration Models, the Contractor shall permanently mark the correct American sizes and widths, the contract number (Example: 04-D-1234), and the company or brand name on the inside of the shoe on the interior of the tongue. The marking may be in the form of a label and shall be done in accordance with acceptable commercial practices, and it shall not reduce footwear functionality. The shoe shall contain a manufacturing tracking lot number and/or a born date.

Unit packs will include Management Control Number or National Stock Number and Universal

Product Code bar codes as specified in the contract. Each symbol must be human and scanner readable.

3.7 Toxicity. The finished shoe shall not present a health hazard and shall show compatibility with prolonged, direct skin contact when tested as specified in 4.5. Chemicals recognized by the Environmental Protection Agency (EPA) as human carcinogens shall not be used.

3.8 Workmanship. The finished shoes shall conform to the quality of product established by this document. The occurrence of defects shall not exceed the contractor's own quality assurance standards and the quality assurance standards defined by the technical data in the bid package.

If the toxicity requirement (see 3.7) can be demonstrated with historical use data, toxicity testing may not be required (see 6.2).

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of material is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activities within the Military DoD, or within the military service’s system commands. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
