Saucony Endorphin Speed 4

Very good shoe, I'm using it for my threshold and intervals training and it does the job.

I love these shoes, they feel fast and quick. I’ve ran multiple workouts and these shoes really shine between 1500-2 miles. Would highly recommend 

Become addicted to the endorphin line (how ironic), nice roll to the shoe, good cushioning. As an older runner (~60) more interested in staying healthy than running fast this shoe seems to help both. Just wish I could find the older versions to save money.  

I've been running in Endorphin Speeds since the second generation, had a couple of pairs of 3rd gen, and now onto my second pair of 4th gen. There have been some changes between generations but consistently they provide a more cushioned ride than traditional shoes without feeling like a super-shoe or race-day shoe. The use of a plastic plate rather than a carbon plate seems to work well in turning them from a racing shoe to an everyday trainer, and when I go back to an older shoe such as the Saucony Ride, I notice the reduction in cushioning. Durability is good - I replace them at around 650km but they don't actually seem very worn at that point. 

Great show from Day 1! Comfort last the duration of its 350-400 miles and does not go ‘flat’ on you. Looks great. Feels great rides great. A fast everyday trainer and race shoe!

Nice shoe and feels good for pickups and threshold but does not last much longer than 275-325 miles. 

A great lightweight training shoe. I love this shoe for intervals and long tempo runs, great fit and cushion. Don’t recommend for long runs on uneven surfaces.

The Saucony Endorphin Speed 4 is lightweight, sturdy, provides great energy return, and lets your stride be your stride--that is, it doesn't try to impose a stride on you with gimmicks or over-design. If I had one slightly negative note, it's that it's a little snug at the toe box; but that also adds to its quick energy return, so I don't mind it. Honestly, my distance and tempo is so smooth in this shoe that I've considered testing it out in races in place of the supershoes I currently favor. I generally alternate shoes (and shoe brands) every day, as a hedge against injury, but I've taken to breaking out the Endorphins on a more regular basis. Two thumbs way up for this shoe (please, Saucony, don't redesign it!).

There is a lot to like on this. Good turnover and endurance, but never really feel it is that helpful or springy. It also lack the full cushioning of a super shoe.

Have put on about 350 miles and the rubber on the backheel has completely worn away. Other than that, these shoes have been great for workouts, long runs, and even recovery runs.
