i have a low arch and am in the market for a new pair if running shoes, just a pair of trainers. any recommendations?
I have about the flattest feet possible and I have had good luck with the Asics GT-2xxx series but I also have to use orthotics.
My daughter and I both have low arches and use Brooks Adrenaline with Superfeet.
Adidas makes a really good pair of running shoes for pronators. I say, go to a real running store, and have someone fit you and evaluate your run with different pairs of shoes.
I love my vitruvian ProportionIIs. $60, including shipping. Nice flexible forefoot, firm, not spongy Email him with what you’ve worn and liked in the past and your size in THOSE shoes. They run just a tiny bit smaller than Asics and Nike.
I’ve had good experiences with Asics 2110’s and Kayano’s.
Currently using the 2110’s and have a pair of 2120’s ready to go.

I have flat feet and have been wearing Asics Kayanos with good results. The 2100 series are cheaper, though and might work just as well. I’m too nervous about my knees to switch now that I’ve found a good thing.

The shoe-sales assumption is that low-arch=>over-pronation. This is not universally true. I have completely flat (as a board) feet yet prefer a neutral shoe or even a shoe suggested to high-arched people. And I absolutely hate motion-control shoes.
My point is that you really have to try out (as in run a while in) many. You cannot rely on shoe salespeople, especially since they typically only have a few choices available in the store.
another vote for superfeet insoles. I wear mine with Mizuno Wave Nirvana II’s.
Go to a running specialty store. Seriously. While people on this forum include some of the foremost experts in triathlon, based solely (no pun intended) on the fact that you have a low arch, no person on this forum can prescribe you the perfect shoe. You probably won’t find a shoe on sale at a running store, but they’re usually reasonably priced. Anyway, the little extra money you spend on a shoe is worth saving your feet/ankles/knees/hips from the incorrect shoe.
I have the flatest feet possible…used a heavy motion control shoe (NB 1122MC) for a few years but recently switched to the Asics Kayano after getting fitted again after getting stronger on the run. they have been great so far and I really notice the differenc ein weight and comfort between the two shoes. the NB served me well but are heavy and bulky shoes. the Kayano’s are just plain sweet.
But to echo everyone else’s sentiments, go to a good run/tri shop and get properly fitted by someone that knows what they are doing…i.e. looks at the current shoes, has you run up and down a bunch of times, watcheds yoru gait, stride, etc, and tries a few different pairs of shoes on you. You should spend at least an hour in my opinion getting a proper fitting (or at least enough time to find the right shoe, however long that takes).
I hope you are referring to a “mall” store and not a running specialty store.

I agree. Superfeet saved me from plantar facitis (sp).
