Before You Start Breaking In New Running Shoes

What You Need

Safety, Timing, or Context Checks

Check first: Make sure your new running shoes are the correct size and fit *before* you start. Try them on in the shop or at home with your running socks. They should feel snug but not tight, with a thumb's width space between your longest toe and the end of the shoe. If they feel off before you even move, they might be the wrong size or model for you.

Timing is important. Don't plan to break in new shoes just before a big race or event. Start the process well in advance, ideally several weeks before you need them for serious training or competition.

Consider the type of shoe. Trail shoes might need a slightly longer break-in period than road shoes due to their stiffer outsoles and protective features. Always start with easy, short efforts, regardless of the shoe type.
