The Endorphin Trainer is Saucony's first premium fast and light training shoe that combines the innovation, efficiency and a distinctive feel of the Endorphin franchise but engineered specifically for everyday training running runs and high mileage weeks.
Bought these pair back in June and wore them maybe 6 times, ran about 55-60km in these. The back upper heel support already "broke" on the left shoe when I tried to put them on one morning. Now it's flimsy and the shoe doesn't stay as snug each step.
There were other reviews online about quality issues with the newer Saucony's and now I can see why... ):
