NEED FOR SUPPORT!
Most shoes aren't always what is bad, usually it's the crummy insoles they come with! there are many possible reasons that you may have pain in the instep, but try arch supports like spenco polysorb (http://www.
Spenco.Com/products/footcare/poly-sorb) and otc anti-inflammatories (like aleve
). If these don't help, see a podiatrist.
