    1. Best running shoes from Nordstrom?
    2. I’m ready to buy new running shoes. These are my ASICS. See the wear on the thread- mostly outside towards the front. What’s up with this and what should I do? What running shoes do you recommend?
    3. I am nearing the end of c25k app, and my feet are starting to bug me - is there any kind of running shoe you guys can recommend?
