Pearl Izumi EM Road N0 v2 Review
The EM Road N0 v2 is a lightweight, simple shoe that works well. It's not as good as the very best shoes, but it has no real flaws and I enjoy running in it. While the N0 is a little heavier than I'd like given its cushioning, some of the additional weight comes from having more padding in the upper, which may be worthwhile. The N0 is a remarkably natural shoe to run in, and could be compared to running barefoot on a cushioned track. It doesn't get in the way of your natural stride, and makes an excellent every day training shoe. I've rated it as "Highly Recommended". (I use The Science of Running Shoes as the basis of how I test running shoes and what you should look for in a running shoe.)

- . While it's not the best, the EM Road N0 is a worthy contender for your money. It's a little more padded in the upper than most lightweight shoes, and a better toe box than many.
- Asics Gel Hyper Speed is both lighter and better cushioned. . The N0 is reasonably well cushioned, but it's not as good as it could be. For instance, the
- . I measure the EM Road N0 at a 5mm drop unloaded, and 4mm when there's a person's weight in the shoe. I find that this level of drop doesn't impact my stride compared with a zero drop shoe, though regular readers will know that I believe the less drop the better.
- . The EM Road N0 uses a single density of foam with no problematic "arch support". The sole has no gaps that could act as stone traps.
- . The N0 is pleasantly flexible, and it flexes remarkably evenly, unlike many shoes that tend to flex in just one place.
- . The EM Road N0 has a few patches of firmer outsole that are well placed. Some of the outsole is obvious by the different color, but there are also patches that are color matched to the midsole, making them harder to spot. When I first got the N0 I thought it was nearly all expose midsole, but that's not the case. Once you've run in the N0 a bit you can see the outsole as it picks up more dirt.
- cutting open the toe box is recommended rather than required. (I recommend cutting open the toe box of virtually all running shoes, with the exception of a few shoes like some Altra shoes. When you have some worn out shoes, you should try cutting open the toe box. I've found that it's a big improvement, allowing my toes to move naturally and engage for toe off, as well as reducing the possibility of blisters.) . While N0 does not match the shape of the human foot, it's much better than many shoes. There is more room in the toe box and
- . The upper is moderately thin, inflexible and mostly seamless. There is a reasonable amount of padding around the rear of the foot, plus more around the ankle opening. For such a light weight shoe, it's better padded than you'd expect.
- Asics GT 2000. . The EM Road N0 has a traditional tongue that is has a tab to attach it to the laces. The tongue is extremely well padded for such a lightweight shoe .The tongue is nearly as well padded as the much heavier
- . The laces on the N0 are one of the few annoyances. While the N0 has traditional flat laces, they are slick and come untied easily. I've had more problems with the N0 laces coming undone than any other shoe I can remember. (This is the only negative change from the original to the v2.)
- . The N0 has only the slightest of heel counters, and certainly nothing that would dig into your foot.

Here are some direct comparisons with its potential competition.
2.1 Pearl Izumi EM Road N0 Original and v2
The v2 update is relatively minor, but the improvements are worthwhile. The shoe has become a little lighter while getting more cushioning, a nice achievement. I've enjoyed the v2 even more than the original shoe, with the notable exception of the laces that seem to delight in coming undone me to run.
2.2 Pearl Izumi EM Road N0 and Asics Gel Hyper Speed
The Asics Gel Hyper Speed is one of my favorite shoes, and it shows up the weaknesses in the N0. While the N0 is a good shoe, it's not as light or as well cushioned as the Hyper Speed. The N0 is better padded, but I've never felt the difference in comfort in practice.
2.3 Pearl Izumi EM Road N0 and New Balance RC5000
The N0 is reasonably light weight, but the New Balance RC5000 is quite stunningly light. The RC5000 is less than half the weight of the N0, but nearly as well cushioned. Of course, the bare bones RC5000 is not for everyone as it provides just enough cushioning to improve Running Economy, but no more. This makes it the most efficient shoe I've found, but the minimal cushioning my not be sufficient for you. However, if that's a problem for you, then the N0 may not provide the cushioning you want either. (Note that the updated New Balance RC5000v2 is slightly heavier than the original, but much better cushioned.)
2.4 Pearl Izumi EM Road N0 and Asics GT 2000
I tend to compare shoes against my benchmark "normal running shoe", the Asics GT 2000. The GT 2000 weights nearly twice as much as the N0, but most of that extra weight is in the form of over engineered features that The Science of Running Shoes indicate are more likely to cause problems than solve. There's quite a bit more cushioning with the GT 2000, as well as somewhat better padding in the upper. However, the N0 won't attempt to interfere with your stride, or encourage you to heel strike like the GT 2000. The GT 2000 helps show just how good the N0 is; it's just not quite as good as the best shoes.
3 Cushioning and Shoes
It's intuitively obvious that the cushioning in a shoe will reduce the impact on your body when running. However, The Science of Running Shoes indicates that the reality is rather more complex. While slight cushioning may reduce the effort needed to run by improving your Running Economy, most scientific research indicates that more cushioning does further improve Running Economy. In addition, cushioning does not generally reduce impact and may actually increase it. This is counterintuitive, but is likely to be due to the way a runners mind and body adapts to softer cushioning. Unfortunately, the scientific evidence is far from complete and it's hard to give clear recommendations. I believe that some runners will prefer more cushioning, while others prefer less, and typically those running further have a fondness for greater cushioning. I also believe that a shoe should be as light as possible, and a shoe should justify its weight with the cushioning it provides. My advice is to decide what level of cushioning you're looking for, and then find the lightest shoes that also fit well and are comfortable.
