Best Way To Break In Boots. A full grain leather boot will take longer to break in than suede or fabric boots because leather is naturally a lot stiffer. Pour water into two zip-lock bags until they are about your foots size. Plus you want to keep the experience as bearable as possible. Then you place the bags into your climbing shoes and lace the shoes loosely.
Fill two plastic freezer bags with water and place them in the toe of each shoe. Then stick your shoes in the freezer overnight. As a rule of thumb the heavier the boot the longer it will take to break in and the lighter the boot the quicker it will be to break in. It may take 2-3 short hikes to get your most rugged boots fully broken in. Keep them on in the first weeks that you wear your new shoes. Not only will leather conditioners extend the life of your boots overall they can help soften the leather making the break-in a bit easier on your little piggies.

Use Heat First you have to make sure that you are able to heat things up. The water will freeze and expand to stretch out the toe. Mash the heels of your new boots by stepping on them or crushing them with your hands. The loosened leather fibers will adjust according to the shape of your feet as they start to dry up. Take a bucket of warm water and soak in your new boots in it for 30 minutes to 1 hour depending upon the quality of your leather boots. After spraying you should dry your boots by the natural wind.
