I'm running my first marathon in the fall and I don't know what flats to wear. I train in the streak 3 with soft orthodics for my PF. I need to wear the orthodics in whatever flats I pick. I was hoping for something lighter than the Streak 3, like maybe the streak xc2 or xc3. The othodics add a little cushion and heel-toe drop to my shoes so I'm thinking I'll be ok with a thin sole. I have a pair of original streak xcs as well, but my foot doesn't feel great in them.
Thanks for any input.
