RUNNING SHOES: HOW, WHAT, & WHEN ~ GUEST BLOG BY DR. KIMBERLY DAVIS

DR. KIMBERLY DAVIS from RUNLAB™ give us some insight into Running Shoes: How, What & When

HOW OFTEN DO I NEED NEW SHOES?

Probably more often than you think. We recently had a great guy come into the clinic with a hole in his shoe so big that his pinky toe was sticking out because…wait for it…the school pig had chewed on it a few weeks back. Yes, a few WEEKS back. Another lovely woman came in last week wearing Newtons with so little heel left on them that it was causing her to lean backward when she ran (in case the irony of this is lost on you, Newton’s big claim to fame is that they "teach" you to run on your mid/forefoot..a topic for another day). Even if you have managed to achieve sound biomechanics (rare), are extremely light weight (also rare), and a low mileage runner without a pet pig, it is still important to remember that your shoes have a shelf life. Those sweet (rad?) neon and splatterpaint Nike knock-offs you bought for 39.99 from TinyHandsTinyPrices.com may look really cool, but they probably aren’t doing you any favors from an injury prevention standpoint. Most people wait until they start to notice nagging pains before they think to replace their shoes, instead of doing it before the issues pop up. EVA foam hardens after 1-1.5 years, meaning that when you buy older model shoes on clearance or online it is possible for them to be “worn out” before you ever run in them. Most runners should replace their shoes every 300-500 miles depending on the weight of the runner and the efficiency of their mechanics. This means every 5-6 months for the average recreational or very lightweight runner, and every 2-3 for the higher mileage or heavier runner, and this assumes you ONLY RUN in your running shoes, not wear them to work or to the gym.

WHAT ABOUT ROTATING THROUGH SHOES?

I am a huge fan of this concept. Not only does it allow your shoes time between runs for the foam to “bounce back”, but different types of shoes give you different feedback from the ground, and in my opinion, this is always a good thing from a neuromuscular standpoint. Your body adapts very quickly to a learned stimulus. By giving it different signals you are forcing it to constantly respond to outside stimuli instead of just “going through the motions” with learned patterns. I personally rotate through several shoes depending on the type of run and how fatigued my body is, and I find it works very well for keeping my body engaged with what is going on between my foot and the ground. If you would like some guidance on this please feel free to call us or stop by and chat. Everyone that works at RunLab is a dedicated runner and we love talking shop!

HOW DO I CHOOSE THE RIGHT SHOE(S)?

If you answered: "Well obviously, I choose the shoes that will match my tutu for the Goofy Challenge", then you my friend could probably get a job in any number of running retail stores...but I digress. Choosing the right shoe is much more complicated than most people think IF you have suboptimal structure, range-of-motion, and/or biomechanics, which most non-elite runners (and even many elite runners) are challenged with. "How do I choose the right shoe" is the eternal question that every runner (and shoe company, and retail employee) wishes had an easy answer, but at the end of the day...it doesn't. At RunLab, we feel very strongly that it isn't so much about the shoe as it is about the foot that inhabits the shoe (and the knee and the hip and the body that live above the foot and for some reason get left out of most types of "gait analysis" done in shoe stores). Most elite runners with sound biomechanics can run in almost anything they want to run in within a certain range, typically avoiding extreme stability in most cases. They aren't great runners BECAUSE of the shoe, They are great runners because of the work they have put in on the strength side, and often because of the genetic gift they have been given on the structural side. Back to the question. First and foremost, if a shoe doesn't feel good in the store, it won't feel any better when you run. Second (maybe even first) stop choosing shoes based on color! Base your choice on what works with you structure, goals, foot shape, etc. If you fall outside the "norm" structurally, meaning you have bunions, very high or very flat arches, knock knees, are bowlegged, have retroverted or anteverted hips, super tight hamstrings or calves, etc, or if you have a history of injuries or trouble finding shoes that work for you, get a gait analysis. And I don't mean the kind where somebody watches you run for 10 seconds down the street, looks at your foot/ankle, and then starts talking about how much or little you pronate or supinate. That isn't a gait evaluation folks! A good gait evaluation should look at your entire body from multiple angles, ideally, both in shoes and barefoot, and should factor in what is happening with your unique structure, range-of-motion, goals, strengths, and limiters. This is not something most people have expertise in doing well. Think of it in bike-fit terms, you can get your saddle height adjusted, OR you can go through a lengthy process that looks at all the necessary angles and takes your individual needs, foot position, femur length, tibia length, reach, etc into account. Both of these things might be referred to as a "bike-fit" but one of them clearly takes your unique structural and functional makeup into account and requires expertise in biomechanics to really fit you properly. Gait evaluation is the same way. Remember: understanding what could go wrong down the road through thoroughly understanding your mechanics is a heck of a lot cheaper than the rehab to fix the issue when you break. Just sayin.... :)
