Saucony Endorphin Pro 4 Review
By Andrea Myers and Matthew Klein
Since version 2, the Saucony Endorphin Pro series has undergone major changes. Part of that is the company switching to two-year cycles, allowing for greater development time. Version 3 was a drastic change that finally brought an incredibly bouncy midsole to this series. Although said to still be PWRRUN PB, the mixture was clearly different. Some liked the snug fit and bouncy ride, while others were torn. What was challenging was the similar specs to the Endorphin Elite, despite the two shoes being different. The Endorphin Pro 4 changes the entire shoe while keeping some elements around. A new geometry, a top layer of PWRRUN HG, and a brand new upper with more volume are just some of the changes to Saucony's most recent version of its original super racer.
