Running Tip #12. Many runners buy shoes that are too light, small, or stylish. Distance running requires support. Use lighter shoes only after getting used to them. Feet swell when running so go 0.5 - 1 size up. Replace every 400 miles or based on wear & tear, and use a shoe with 50-100 miles for race day.
Pro tips: Use a parallel lacing technique to increase comfort. And try a pair of toe socks if you get blisters as they eliminate skin-to-skin friction. I always run my marathons in them!
