So you've got a new pair of running shoes and you want to break them in a little bit. Well there's two sides to this. First, when you leave the store with your new pair of running shoes, they really should fit. You shouldn't really have to break them in. But at the same time if you have a long run or a long race coming up maybe you buy your shoes on Tuesday or Wednesday but you have a long run of six, seven, maybe even ten miles over the weekend you don't want to wear that brand new pair of shoes for that long run. Try to wear the shoes walking around maybe walking around the house, walk around your neighborhood a little bit, maybe go for a short run, two to three miles. Try to see if something is rubbing causing blisters or causing chaffing somewhere in your feet. you can prevent that by wearing dry fit socks. Try to avoid wearing cotton socks which can cause blisters and chaffing by holding in that moisture and that sweat. So again, walk around a little bit, try to do a short run before you do that long run, before you do that long race so that you're not in the middle of your race with some brand new chaffing that you weren't really sure was going to be there.
