My gaiters were delivered very promptly and I did an 8 mile hill walk wearing my new gaiters the next day. They are very lightweight and a very neat and secure fit, with no problems with anything coming undone on my walk. I bought the size one. I am 5ft 3inch tall, size 12 and boot size 38 Scarpa Terra GTX. The gaiter strap which fits under the instep is easy to adjust. The gaiter zip is a bit difficult, but once done up is fine. These gaiters are designed for use with leggings I believe, and would be difficult to get on over thicker walking trousers.
Very pleased with the look and fit of this new bit of kit, and can thoroughly recommend FreshAirJunkie for service and delivery.
