Glad they've come out with the 2.5 now. Don't mess with these even if they're deeply discounted. I love Altra, but for some reason they have had a hard time getting the upper in the toe area right with the One. Too shallow, too short, poorly fitted. Love the width, but my toenails have gotten beat up. Love the outsole, too. I hear in the 2.5 they've addressed this part of the shoe. That's where I'm headed next!
