Danner USMC RAT Temperate Boot Late Version (Made in 2009) This is a pair of Danner RAT boots. Size is US7, which is 25.0 cm in Japanese sizing. I believe this is a rare size. I purchased these new and wore them only once or twice for touring, so they are almost unused. U.S. Marine Corps issue model. Waterproof (GORE-TEX liner) For temperate climates (not for extreme cold) Vibram USMC combat tread "Late version" sole specification Why there is no GORE-TEX marking: Around this time (2009), many U.S. Marine Corps RAT boots were equipped with GORE-TEX liners but did not display the marking on the exterior. Actual military issue items often have different markings than commercial versions to avoid trademark issues.
