I developed plantar fasciitis last year and got orthotics fitted this Winter.  My doctor told me I needed to wear shoes with a firm base which don't twist too much and with excellent arch support.  He approved of these and my feet are so happy in these.  And they're very breathable and light which is great for those who run a little warm.  I ordered my regular size and they fit perfectly.  I'm very happy with my purchase & amazon had the best price (& you gotta love the free 2 day shipping with amazon prime).  I'll be back for more Asics when these are worn out.
