You are right. 13s never had full length zoom like the 12s. These do have forefoot and heel zoom, like og 13s. These are just thiner bags then a remember.
I feel the same way about the weight. I don't remember 13s being this light. I don't mind the glossy sole, but the quality really seems low. Padding is super thin on the sides and the zoom units don't feel great either. Think these are going back.
