I had version 1.0 of this moc. I preferred his wider toe. They are slightly narrower than the actual D width. So be careful when replacing older, wider models. However, the durability is undeniable and after 6-8 months of wearing I am very happy with them. They also work well with my custom made, right sized orthotics. They begin to stretch (expand). I wore the last pair almost every day for 6 years. Hope these last as long.
