So Comfortable
Love this shoe. IMO, this model is much more comfortable than the newer model.
Comfy shoes
I own a pair of adidas ultraboosts, and I'm always afraid that shoes won't fit when ordering online because I can't try them on beforehand, but these fit perfectly! True to size with enough wiggle room in the toe box to not squish my toes when running. The Boston Marathon branding is a plus :)
