My fifth pair of Altras headphones. Fits right out of the box. I have 2 weeks off. Not happy with the feel of the upper compared to the 4.0 Torin. The lace length is perfect and the fit is always great. Light feeling. Will start running next week to test ride. I like the tongue of the boot, it flows right into where the front bone of the leg meets the foot. I will publish soon.
