These are an inexpensive, well fitting gaitor. I've had a pair for a few years now, and use them mostly for summer and fall hiking. They fit closely around my boots and ankles, and stay upright after miles of hiking.
I've used them on different pairs of boots, and the wide front velcro strap and bottom strap easily make up for the different sizing requirements. One of the best features I've found about these gaitors is the set-and-forget adjustments to the top cinch cord and bottom strap. Once set for a particular pair of boots, they can be quickly wrapped around your legs and velcro'd in place. These do not require lacing a strap through a buckle every time you put them on. It is also very quick to adjust the top cord, if necessary, using a single cord-lock; and being a bungee style cord it stays snug yet flexes with your leg.
Mine have began to wear out on the inside area between the boots, but this is to be expected, and I've successfully patched holes with iron-on patches coated with shoe-glue, extending their life for another year or two.
The downside: These will make your ankles sweaty on a hot day, but I prefer that over dirt, rocks, mud, and water inside the boots when stomping down trails. The only recommendation I have is to cut the little ball off the end of the top cinch cord before using them. It has a habit of catching on every stick, weed, and twig along the trail and tripping you up or snapping back with a vengeance. They're completely unnecessary and won't be missed.
I planned on purchasing another pair of these from REI, but they are currently not available. When and if they do sell them again, I will gladly pick up another pair.
