The Air Force boot straps are for the airmen that pave the way, Barrier Breakers. These fourth generation boot straps are made with nylon clips with sure-lock technology and durable rubber straps to keep your pants in place like no other product before it. Because of the materials that are used they perform in the rain as well as a muddy field. The manufacturer went with a self-adjusting rubber strap so it did not get in the way of the operation of the motorcycle. Another reason for not having an adjustment is that our straps will not become unadjusted and drag while you walk. Our 4" strap is perfect for women whereas the 6" strap is made for the average man's shoe sizes. The 4" strap stretches to roughly 7" and the 6" strap stretches to about 11". Our new clip is made with high quality nylon with a heat treated metal insert for a sure-lock experience. These clips hold stronger and last longer than the typical suspender clip that has been used as the industry standard. We even double machine pressed the decorative emblems onto the clips for durability which will keep the emblems from spinning on the clip with age. The new clip even has the ability to interchange new emblem designs without having to buy the whole strap, which will keep cost down if you break one or just want to have a couple different styles. These straps are sold in a set of 2 and come with a 6" strap.
