Underpornator runner using overpronator shoes?

Question

few days ago I was fitted in fleet feet,

I am 180lbs,underpronator, and high arch

the associate brought 3 pairs of shoes for me

A mizuno,new balance and a brooks BEAST

Sorry I forgot the name of MIzuno and Newbalance that I tried. They were suppose to be for underpronator

because the associate watch me walk and ask me few question

After i jogged a lil bit outside their store with 3 different shoes

I find the mizuno uncomfortable, but great cushioning.

The new balance is comfortable but the cushioning in the forefoot is not good, while find the brooks beast has the perfect cushioning I thought there was something wrong with the outsole because it is very soft,after i jogged with it I think they were the "ONE".

THe associate did not warn me that it is for overpronator,but I bought because It feels good. I already ran on them for 2 days, 2 miles each day on the street and I find them very very cushioned even it doesnt support my high arch feet

Answer 1

I think your question is basically what will happen if an underpronator runs in a shoe designed for an overpronator?

Possible problems would probably manifest on the outside of the leg.  Peroneal tendonitis, illotibial band syndrome in the knee, pain on the outer hip area, etc.  

That said, I've seen underpronators run fine in motion control shoes; I've also seen fairly severe overpronators do fine in completely neutral shoes.  If the shoes feel comfortable and you're not having any problems with your legs or feet, use what works best for you.

In general, the most important thing for a person with a high arch or who underpronates is making sure the shoe offers enough cushioning.

Answer 2

The Brooks Beast for a high-arched underpronator is exactly the opposite shoe I would think a good shoe sales person might recommend.  Often runners, even flatfooted overpronators for whom the shoe was designed, say that while they appreciate the motion control the shoe offers, it's a bit heavy and they kind of feel like they are plodding along in it (although it does offer great motion control).

I've never owned the Beast, so I can't say for sure, but usually a motion-control shoe has less padding, because too much cushioning leads to instability with a flat foot.

But what you need is maximum cushion, since a supinating high-arched foot lacks the normal amount of flexibility of a "normal" arched foot.  In fact, in one study I remember reading that the high-arched feet were the ones that developed stress fractures and other injury, more so than flat feet.

Since the Brooks Beast is deliberately designed for a flat foot, it has a low arch support inside, as you have discovered.  Most high-arched feet are more comfortable with a high-arched innersole.

If you've been using this shoe and love it, I would at least suggest inserting a cushy Dr. Scholl's kind of soft arch support, right over the innersole that comes with the shoe.  That way, you can wear the shoe you like while providing some extra height to support your high arch.

Let us know if you try this, how it works?  Good luck!
