If you are buying new hiking boots before a trip there is a break in period before the boots get comfortable and you don't want to go on a long backpacking trip with brand new boots. Time will depend on the person and how much time they can spare for breaking in and distance can depend on the terrain but there should be at least an average value for this.
On average how long/how many miles do you need to put on a pair of hiking boots before they are broken in?
