Review title: Best knee savers!
Product review: I run about 30 miles a week. I wear Nike trail running shoes and I've had them for about a year. Not wanting to purchase new shoes, I thought I'd just remove the insoles and try these Spenco's. I cannot BELIEVE what a difference they've made! My joints don't ache at all and my lower back never gives me any grief now. The only thing I've changed are the insoles of my shoes...not the terrain I run on, or the speed or my distance so I can only assume my Spenco's are to "blame". :)
