If you are a racewalker (or a mere runner*, for that matter), you have come face to face with age-old shoe dilemna (or "dilemma" as it is apparently now officially spelled: I won't go into the dilemna dilemma here). But what if you could solve your foot problem using the shoes you presently have? Sometimes it isn't the shoe, but how you're lacing it that is causing the problem. I learned a long time ago that specialty lacing allows my severely messed-up left foot to function. I found New Balance's guide to specialty lacing through a link somewhere else so long ago that I forget where:
http://www.newbalance.com/lacing-guide/ By using the lacing technique for bunions and heel slip I had what almost amounted to a custom fit! I have been religiously using this method ever since on all my shoes.
Since then, I've come across a few other webpages along these lines. Here's one for hiking boots for example: http://www.backpacker.com/gear/5245 .
Then, of course, if you're more the stylish type, you could try some of these (http://www.fieggen.com/shoelace/lacingmethods.htm) very artisitic patterns just for fun, LOL!
* sorry - couldn't resist giving back a little of what we racewalkers get all the time! We seem to be the Rodney Dangerfield of sports - we get no respect!
