I keep coming back to these shoes because not only are they cute as a button, they're the very best running shoes I've ever had. I've run hundreds of miles in my Flex '16s and I dread the day I stop being able to find them anywhere -- I hope the '17s or maybe some future '18s are half as good as these. I've got a worn, dirty pair that I've retired from running and use now at work and for hiking, and I use my bright, fresh, new pair for the gym. Just obsessed. These shoes were made for my feet, and I'm so glad I could find another pair here all these months later.
