{{DISPLAYTITLE:Saucony Endorphin Racer 2 Review}}The original Endorphin is an ultralight outstanding running shoe that provides , providing a surprising level of cushioning at an ultralight weight. I had incredibly high hopes for its this second generation, with reports of improved cushioning and only slight weightgain. Obviously there's not as much cushioning as many heavier shoesThe forefoot was also changed to use TPU foam, but you might which can be surprised by how far more resilient and long-lasting, as well it does for itselfas provide rather more bounce than traditional EVA foam which is still used in the rear of the shoe. Of courseSadly, while the reports of the weight gain were true, the cushioning is actually quite a lot worse than of the original shoe this light may not provide enough cushioning for everyone, but . My initial runs in the endorphin 2 were a little slower than I'd recommend trying it out if have expected, and the shoe didn't feel cushioned enough to give me improved Running Economy youcan get with modest cushioning. My initial impressions of this being more of a minimalist rather than optimal running shoe were confirmed by some later calculations of the shoes measured cushioning. I're a reasonably efficient runner looking for an edgeve rated the endorphin to as "worth considering", as I think there are far better light weight running shoes on the market, including its predecessor. {{H:WhatToLookForInShoes}}

* {{H:WhyBuy}}. If you're after an ultralight, fast shoe, this is a prime candidate.* {{H:cushioning}}. The Endorphin 2 uses Saucony's EVERUN under the forefoot, which is remarkably well cushioned given its weight their form of only 4TPU foam.1ozTPU foam tends to be much longer lasting than traditional EVA foam, and it can be rather more spring the, but unfortunately quite a bit heavier as well. There is obviously a lot less cushioning than youI've generally found Saucony'd find in s implementation of TPU to be inferior to other shoes that would be normally be considered a light weight like companies, especially when comparing to the awesome [[Asics Gel Hyper SpeedAltra Escalante]]. I found the endorphin 2 to be rather under cushioned, but even that and therefore slower than a slightly better cushioned shoe weighs half , so I'm classifying it as a minimalist shoe, though it's probably got a little too much again. The Endorphin has enough cushioning midsole for most runners looking for me to consider it an optimal rather than a minimalist shoe. The lack traditional EVA foam used in the rear of the midsole is rather firm a than is typical, probably to match the cushioning characteristics of the TPU foam in the forefoot more closely. It's hard to see the dividing line between the two types of foam, but if you look closely at the photos of your see a minimalist shoe reduces Running Economydiagonal line, but and the Endorphin allows me to run with just TPU foam in the same biomechanics forefoot as I would in a far more cushioned shoemostly smooth finish, where the EVA foam has a crosshatch pattern embossed on it.* {{H:drop}}. The Endorphin 2 is zero drop (in fact, I measure it with 1mm of negative drop), which is nice to see. * {{H:structure}}. The Endorphin While the endorphin 2 uses a single density two different types of foam with no real "arch support" , these are not intended to cause problems. The gaps manipulate your running form in the midsole have never been way that a stone trap for me, and I don't think they should be an issuemedial post would. These gaps will allow water to drain out more quicklyIn fact, which the endorphin is nice for running through puddles (or even stream crossings)a remarkably neutral shoe, with a fairly flat shape under the heel, and very little in the way of rise under the arch of the foot.

* {{H:outsole}}. The Endorphin 2 has lots a layer of smallharder, hard plastic lugs slightly sticky rubber outsole over the forefoot and extreme edge entire surface of the heelsole. These This outsole is perforated with lots of triangular holes, which are not easier to see as black triangles in the type rear of lugs you'd find on the trail shoefoot, but are intended to provide extra grip if you look carefully you can see these on asphaltthe forefoot, something they do nicelyrevealing the TPU foam below. For fast running on wet asphaltThese gaps in the outsole help with flexibility, these lugs are greatand I found the material they've used in the outsole to have pretty good grip. * {{H:shape}}. Like most running shoes, the shape of the Endorphin does not match the human foot, and narrows in but the toe boxendorphin is actually rather worse than most running shoes, and as noted above, I had to a real problem finding a good fit. [[Shoe Modifications| cut Cutting open the toe box open]] to prevent toe problemshelps somewhat but the fit is still pretty funky. {{H:TryCuttingShoes}}* {{H:upper}}. The upper is thin, inflexible and seamless with absolutely no padding, but I found it surprisingly comfortable. There upper is nicely moderately breathable, with some holes midway up the a fine mesh reinforced by a honeycomb pattern of slightly thicker material over , as you can see in the midfootphoto below. I was surprised how tough the upper is given the lightness of the shoe<br/>[[File:Saucony Endorphin 2 Upper. jpg|center|thumb|300px|]]* {{H:tongue}}. The Endorphin 2's tongue is sown to the upper on the inside edge, which helps keep it in place. Just like its predecessor, I found the tongue is so thin I had problems avoiding it rucking up when I put the shoe on, but it never caused an issue during the run, only beforehand. * {{H:lacing}}. The Endorphin has traditional flat laces that are a little thinner than most, probably to save weight. I found that they stayed tied nicely, and there is a small amount of elasticity in the laces, which probably contributes to the comfort of the shoe.
