I've been doing single-leg deadlifts for about a month now and have finally worked up to a decently heavy weight. Each time I've added weight I've found that it is my balance that needs work more than my strength, however, the balance improves quickly and I'm able to add more weight easily, sometimes even in the course of just one workout. But now I am having a much more difficult time with balance and seem to be a bit stuck because of my flat feet.
I am completely flat-footed. If I allow myself to stand "naturally" I have no arch at all. As a child I wore arch supports for a few years but eventually took the advice of a (possibly ill-informed, as I grew up in a small town) chiropractor and started correcting the problem by consciously faking the arch and basically pronating just a little bit.
I am unsure if this artificial arch is a good thing but I have no trouble maintaining it and have no pain or problems standing for long periods of time, walking or running (my running shoes are the only shoes I have that have much arch support). My shoes wear evenly on the balls but are a little more worn on the outside of the heels.
I had been driving through the heels for the deadlifts and having no issues as far as how to balance my weight on my feet but now I am finding that it is as if I cannot find a proper stable surface to drive through. When I try to keep my weight on my heels my arches want to collapse. If I allow my weight to be balanced more on the middle or ball of my foot I just feel plain unstable. Letting my arch fall flat feels wrong, so I keep trying to pronate and raise the arch but that makes balance even more difficult. The whole process is confounding and frustrating.
Can anyone offer me some advice? Should I get shoes that have more arch support? (I currently lift in Converse All-Stars). Should I allow my arch to fall? Or should I keep trying to somehow keep my artificial arch and yet drive through the heels? (Maybe I just need more practice).
Thanks in advance for your replies.
