The whole shoe is built on a bed of PWRRUN PB midsole foam that delivers endless energy return while providing the cushion you need for efficient landings.
Within the PWRRUN PB foam is a full-length nylon plate that creates the stiffness you need to generate forward momentum without any added weight.
The nylon plate is unique in that it is much more flexible than a carbon fiber plate, making the Endorphin Speed 2 a great shoe for those we are just getting started running in a plated shoe.
No matter the plate material, a plated shoe provides the stiffness necessary for propulsive strides, and can increase the energy return to your legs. This means you feel fresher, and faster, longer.
Fleet Feet reviewers agree, the nylon plate stands out in the Speed 2, making it one of the more accessible models of the Endorphin collection.
“The biggest thing that stood out to me about the Speed 2 was the nylon plate. I was surprised at how flexible the shoe was even though it’s plated, but it still provides a ton of propulsion over long runs and speed work,” one reviewer says.
