Saucony's Endorphin Collection has been an absolute success so far. Of the lot, the Endorphin Speed family has always been the biggest fan-favourite, as it sits in the Goldilocks zone of comfort and performance. And with the Endorphin Speed 4, the Waltham, Massachusetts-based company seems to have perfected the formula of what makes a peppy daily trainer good enough to wear for – well – everything.
Like thousands of other runners, I liked the Saucony Endorphin Speed 3; it's a decent trainer that does what it says on the box. It might not be the best running shoe out there, but it's definitely good enough as a workhorse-style trainer.
