shoes

Going shoe shopping this weekend, I purchased reeboc zig nano's in March, loved em for the arch support (wk in the medical field on feet all day) and also sales lady recom them for shin splints on treadmill. They did great for both areas. HOWEVER, they have already worn down as far as sole support and have holes on top of both shoes where lil toe is and obviously cannot wear em at wk now and time to get more. Have heard great things about Asics, use to wear Nike shocks they were ok for work, but I turned my heel a lot in them and feel heavy on treadmill.
Any suggestions???
