The 1300 is not that comfortable of a shoe. It feels stiff on feet and there is not cushioning. It's stable and supportive, but the lack of cushioning makes it an overall uncomfortable shoe. It's ok for regular lifestyle wear, but if you're on your feet constantly, then it's not for you.
The 1300 features ENCAP with a stiff foam midsole and an overall flat midsole and outsole shape.
