I had the spenco polysorbs then purchased the NEW BALANCE IPR3030 following THE INSOLE STORE rep’s recommendation, for my wife,who, like myself stands and walks on concrete all day and they just looked really comfortable so I purchased a couple pair for myself.
I work 12/7 on concrete and the IPR’s are like heaven. I highly recommend the New Balance Insoles with Metatarsal Pad and the Insoles recommended by The Insole Store.com
