I am new to the forum…I’m doing my first triathlon this weekend so I’ve been hanging around here picking up free tips for a while.
I have been running for several years, with 10-12 marathons under my belt and a best of 2:37.
Triathletes by their nature seem to be gear freaks and this holds true for their shoes too. They want the most sophisticated technologically advanced model available when a simple lightweight cushioned shoe would work much better for most of them.
Many elite runners train year round in the lightest shoes they can find i.e. flats. I would too if I could get more than 100 miles out of a pair. I wear NB 833s which are a little over 10 ozs, cushioned and simple…no medial posts, air pockets, motion control devices or other bells and whistles. Just a light upper and an EVA midsole. I get about 400 miles out of a pair…I’d prefer 700 but what can you do?
Biomechanics are a lot more complicated than why your foot hits the ground and pushes off in a particular way. There are a thousand small causes and effects which make you run the way you run…same as your swim stroke…if you lift your head your feet drop…in running if you artificially change your foot plant something else in your stride will change.
The most obvious biomechanical changes are caused by pace. I’m a midfoot striker at anything above 5:45mm when I drop down to 10K pace I’m more of a forefoot striker, and when I’m racing a 5K I’m up on my toes the whole time. The shoes you wear don’t know how fast you are running and may help correct a problem that you have running 8:00mm but create problems if you run at 7:00mm pace.
If you interfere artificially and doctor your stride with motion control shoes you’ll never know or be able to correct the biomechanical deficiency that is causing the problem in the first place.
The more miles you run the more your body will make minute adaptations to find the best and most efficient stride…practice makes perfect. Again I’ll use a swimming comparison…if you swam 3 hours a day for a year you’d eventually become a pretty proficient crawler despite never having had a lesson or being drilled…your body would unconsciously make the adaptations towards the most efficient method for forward propulsion.
The same holds true for running. Your body will correct itself if you give it time and be patient. If you take short cuts and strap on 14 oz clogs you’ll never be a naturally efficent runner.
The purpose of the Nike Free is in a sense to wean people off overly intrusive shoes that weaken feet. You wear them a few times a week and your feet slowly adapt back to their own natural plant as opposed to an artificial one generated by clunky shoes.
I just spend all my spare time in Tevas…does the same thing.
