Someone who wears the Adrenaline GTS 9 could also wear the Trance 9, as they provide support for the same type of foot: a moderate pronator. With that said, there are a few key differences between these shoes:
– One of the biggest difference is the fit. The Adrenaline GTS 9 has its signature "midfoot wrap". (“Midfoot wrap” is how the upper of the shoe conforms to the middle of the foot. Not just the arch, but also the side of the foot. With a snug midfoot wrap you get a shoe that feels “at one” with the foot.) In comparison, the Trance 9 can feel like it has a wider toe box.
– The Trance 9 provides much more cush in both the heel and the forefoot by using our biggest Hydroflow XL pad.
– The materials in the upper of the Trance are plusher and softer, which adds to the cost.
