(We stock a tight assortment of various models and sizes of the best Ice Climbing and Technical Mountaineering boots available at our Feathered Friends Seattle Mountaineering Store.  Due to the high expense of stocking modern technical boots and the ever increasing frequency of model changes by the manufacturers, it is no longer practical for small local family run mountaineering stores like ours to keep every size of every model in stock.  These types of boots frequently require us to special order your size.  Please stop by our store and allow one of our experienced staff members to help determine the best mountaineering boot model and size for your needs.  If needed, we will order a boot or two for you and cover the shipping cost of getting them to our store for you.  Our staff will then help you make your best decision, and then we will cover the return shipping fee back to the manufacturer if they end up not providing a good fit for you when you come in to try them on in our store.  We really appreciate your willingness to support our mountaineering store by allowing us to help fulfill all of your mountaineering footwear needs!)
