3. REQUIREMENTS

3.1 First articles. When specified (see 6.2), a sample shall be subjected to first article inspection in accordance with 4.2.

3.2 Recycled, recovered, environmentally preferable, or bio-based materials.

Recycled, recovered, environmentally preferable, or bio-based materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs.

3.3.2 Counters. The heel counter shall not include any rigid plastic components, and must be soft and pliable, yet durable enough to last for the life of the shoe. This yields a shoe with lighter weight, greater comfort, and less interference with natural foot motion.

3.3.3 Laces. The color of the laces shall match the color of the exterior of the upper unless otherwise specified in the contract or solicitation. The length of the laces shall be a minimum of 50 inches for a men’s size 9R (D). Length may graduate up and down, with the sizing, for both men’s and women’s shoes.

3.4.1.8 Toe box/spring. The shoe shall be made to accommodate the majority of users, and shall include a wide toe box and limited toe spring (i.e., limited “rocker” effect, as when the toe of the shoe is significantly elevated off the ground).

3.4.1.9 Elements. The shoes shall be free from bracing, stability, or motion control elements to include medial midsole posts or upper elements designed to limit pronation.

3.4.1.10 Stack height. The stack height (foot elevation above the ground) will be a minimum of 10 millimeters but less than 24 millimeters.

3.4.1.11 Weight. The weight of a finished size 9 men’s shoe shall be less than 10 ounces. The weight of a finished size 8 woman’s shoe shall be less than 8 ounces. Shoes in the neutral category may be 1 to 4 ounces lighter than the maximum weights specified here, and this is desirable as long as the shoe meets durability and all other requirements.

Shock attenuation shall be achieved through the choice of standard materials and construction techniques used in commercial industry and found in this Purchase Description. 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 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.

3.6 Marking, permanent identification. With the exception of Product Demonstration Models (PDMs), 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 (MCN) or National Stock Number (NSN) and Universal Product Code (UPC) bar codes as specified in the contract. Each symbol must be human and scanner readable.

4.4 Inspection and component testing.

4.4.1 In-process inspection. Inspection may be made by the Government at any point or during any phase of manufacturing to determine whether the components are as specified or operations and/or assemblies are accomplished as specified. The Government reserves the right to exclude from consideration for acceptance any material or service for which in-process inspection has indicated nonconformance.

4.4.2 Component testing. The components shall be tested for the characteristics listed in Table III. The methods of testing specified where applicable shall be used. The sampling plan shall be as follows unless otherwise specified in the contract or solicitation.

The shoes shall be examined with cushion insert inserted. For the pairing examination, the pair shall be examined together. During the inspection for the defects listed in Table IV, the departures from specification requirements listed in the table shall be observed and recorded. Presence of these departures shall not result in the rejection of the lot; however, the plant quality assurance and Government personnel reserve the right to establish and impose lot rejection criteria when either the severity or the presence of these departures warrants such a measure. These additional rejection criteria may be invoked at any time during the life of the contract when the Government judges this action to be in its best interest. Defects of pairing shall be classified as a single defect.

4.4.4 End item testing. The finished shoe shall be tested for the characteristics listed in Table V. A size 9 men’s and size 8 women’s will be used for all tests, including weight testing.

For these tests, the sample size shall be three shoes for each test per lot. Each successful offeror will have the first three production lots tested at an independent laboratory capable of performing the tests as stated in the purchase description and Section C of the resultant contract. The Government reserves the right to draw samples from any lot and perform whatever tests deemed necessary at any time during the length of the contract.
