According to David Brown, a USAT Level 1 certified U.S. triathlon coach, breaking in a new pair of shoes can typically take four to six weeks.
The number of miles ran each week affect the length of time it takes to break in new running shoes. Typically, it takes 40 miles or more to break them in properly.
Breaking in a new pair of shoes is important. This can affect the performance of a runner and might result in injuries if not properly executed.
Before buying a new pair of running shoes, make sure the shoe fits properly and that the toe box is comfortable. If a shoe is fitted incorrectly, you might never be able to break them in at all.
Give enough time to break in the running shoes if training for a race or a marathon as this can greatly affect your performance.
Length of time might vary because every running shoe breaks in differently, just like every runner has a unique running style.
