3.7.1.1 Safe use of your USMC RAT Temperate Weather Boots. “For the safe use of your USMC RAT

Temperate Weather Boots: 1) Wear 1 pair of socks made of wool, acrylic, polyester, olefin, nylon, or lycra blend. Cushion soled socks are recommended. 2) Always wear with one pair insole inserts. In some instances it may be necessary to select a slightly larger size boot than normally worn in order to allow for normal swelling of the feet and the use of insole inserts or cushion socks. Pull on boot, seating heel firmly into place, then lace. Boots should fit snugly but not tightly. There should be at least a 3/8 inch minimum additional length at the toe. If blistering occurs, check to make sure that the boots are fitted properly and that you are wearing recommended socks.

3.7.1.2 Cleaning and Maintenance Instructions. “To Properly Clean and Maintain your USMC RAT

Temperate Weather Boots: 1) Brush mud and excessive dust off boots with a stiff nylon bristle brush and warm water. These boots have a suede finish and are not to be polished. 2) Wipe inside of boots occasionally with a moist rag and let dry. 3) As frequently as possible, dry boots and insert in the sun. If boot becomes wet, empty excess water, change socks, and continue to wear while changing socks regularly. Boots will dry faster when worn than if left to stand and dry. Do not place near intense heat as this will destroy nylon and leather. 4) The nylon side panels of your boots are as strong as leather and will last if cared for properly. Do not use soap to clean your boots. If more stringent cleaning is necessary, only water soluble cleaning products should be used as oil- or alcohol- based cleaning products may damage your boots.”

3.7.1.3 When to Replace the USMC RAT Temperate Weather Boot Outsole. “Your USMC RAT

Temperate Weather Boots come with a replaceable rubber outsole. Do not wear any part of the outsole past 1/16” (in thickness) or permanent damage of the cushioned midsole will occur. The midsole is the soft cushioned material between the rubber lug outsole and the boot upper. To find the repair retailers closest to you visit http://www.vibram.com.”
