The plate is not immediately apparent and the shoe feels very natural and flexible through the gait cycle. Stepping into the shoe, there is a really substantial amount of cushioning to be had. The trampoline bounciness and energy return plays the most important role in making these shoes feel faster. It primarily provides structure and stability to a thick slab of foam that would otherwise feel like a marshmallow. I’m convinced most of the special sauce in these super-shoes is the foam. The stack heights are 33mm rear and 25mm forefoot, for an offset of 8mm. My US mens 9.0 weighed 229g / 8.1oz for one shoe.
The stack height didn’t prove to be much of a problem on canted terrain, either. even with barely any effective lug depth. I tested the Speed on mild gravel and dirt trails and there was acceptable grip. While not very thick, it does provide decent traction and protection for the midsole.
#Saucony endorphin speed review series
It consists of a series of segments which combine to form the standard chevron-shaped lugs. The outsole is a very thin layer of high abrasion rubber bonded to the midsole. Unlike some of the other super high stack models, the Endorphin has a more typical stack height and feels more stable and lower to the ground, in this respect. Sitting atop the whole thing is a thin sockliner with a medium-high arch molding. The nylon plate provides some structure, but it’s not nearly as stiff as the carbon plate on the Endorphin Pro. Taken on its own, the foam has a very compliant feel. The midsole is Pebax foam with a nylon plate embedded in the middle.
