just dayhike in them for about 20-50 miles and make sure you have leukotape in your bag.
if they're eva foam midsole boots (most modern hiking boots) then there is no break in period at all, not required, if they don't feel good right out of the box you sized wrong or have a bad fit or need an orthodic or something.
>>2417335eva foam midsole boots are pretty great because their lifespan is about the same amount of miles as most of the thru hikes in america and they have no break in period.
trailrunners also have no break in period but have like 1/4 the lifespan.
its an important thing, because you don't always have the luxury to break in your boots if they get replaced in the middle of a thru hike. if any anons don't understand the value in not having a break in period.
