If you like the Kinvara 12, the good news is, the midsole hasn’t changed at all. Further, if your foot is on the wider side, you will appreciate the generous new upper. It looks good and has features a breathable engineered mesh, a gusseted tongue, and a well-designed heel counter. Even better is that the Saucony Kinvara 13 is half an ounce lighter than its predecessor. The character of the Saucony Kinvara 13 stays true to its origin and provides a smooth, no-frills, lightweight ride. My 10.5 weighs 7.7 oz. (219 g.) with a 4mm 28.5/24.5mm offset.
