Saucony draped the Endorphin Pro 2 in a single layer engineered mesh upper that keeps the shoe lightweight and breathable. The mesh works with Saucony’s unique FORMFIT technology to contour to the shape of your foot for a huggy, supportive feel.
“If socks could be carbon plated, they would be the Endorphin 2’s. I can’t get over how snug and comfy these are,” says one reviewer. “They feel instantly supportive in the arch and heels, and I feel like the footbed really contours to my foot.”
On top of the FORMFIT technology throughout the shoe, the Endorphin Pro 2 also uses an attached booty-like tongue to dial in on the snug fit. Since the tongue is attached, it eliminates uncomfortable rubbing or moving while you run, and it’s lined with silky smooth material.
“The tongue liner is so soft, I could comfortably wear these shoes without socks. The whole thing feels secure but not stifling,” says a reviewer.
