I have not had to lace lock the shoe and the laces have stayed very secure. The midfoot features a gusseted tongue and laces that lock down the foot far better. This is offset but a high level of cushioning and I did not have any irritation wearing it. There is what feels like a more substantial heel counter. The heel is far more secure with more volume around the collar. The forefoot continues to be a more open mesh that stretches slightly. There are far more overlays in the heel and midfoot, which provide additional security. The upper fits slightly snug like the previous version but with more thickness to the upper. Matt: The Saucony Endorphin Speed 2 fits me true to size in my normal men's size 10. ItвЂ™s slightly heavier, and the new upper and minor construction changes allow this to function even more as a trainer than the previous version. Nathan: Fans of the original Endorphin Speed will be happy to find a very similar experience in this next version. The result is a much better lockdown to this already highly versatile favorite of many. The lacing system, upper/overlays, and the heel layout is updated. A great lightweight trainer/racer for many, subtle changes make for big improvements in the Saucony Endorphin Speed 2.Дavid: The Saucony Endorphin Speed keeps a lot of its original ingredients, but expands upon the upper. Continuing to use a nylon plate, the ride is bouncy and snappy without being aggressive. Although no changes were supposedly made to the sole, the ride feels far more stable than previous while still being a neutral shoe. Tweaks to the upper create a far more secure upper through the lacing, overlays and especially at the heel. Matt: The Saucony Endorphin Speed 2 returns working on the success of the original.
