text: I loved the original Superior model, which is why I am so disappointed with this new &#34;upgrade.&#34; First of all, I had to go up a half size. No big deal there, just a minor inconvenience. But that wasn't the end of it. What the heck did they do with the toe box? One of the best features of Altras is their supposedly comfortably wide toe boxes. They decided to do with out that on this model. I tried to make these shoes work, but after about 100 miles of suffering through (usually after about an hour of running each time), trying to get them to &#34;break in,&#34; I give up. I even used a shoe stretcher (both to widen and increase the upper toe space), to no avail. I always end up with blisters on feet (usually pinky toe).
