Pearl Izumi. It sounds like the name of a new toothpaste (“It will make your teeth shine pearly white!”). But Pearl Izumi means “fountain of pearls” in Japanese, and the company may have produced a pearl of a product in the Road N1.
This is a neutral running shoe with a unique appearance. When I opened the box, I noticed that the blue and yellow colorway Road N1 looks somewhat like a triathlon shoe and a bit like a skateboarder’s shoe. While it is built on a semi-curved last, it hits the eye as being semi-straight, a factor that brings to mind the skateboarding shoe analogy.
The Road N1 weighs 8.2 ounces and has a low heel drop in line with being a minimalist-style trainer-racer. One retailer lists the heel drop for this shoe as 7mm, but it may be irrelevant, as the shoe is said to possess a variable depth midsole (a “dynamic chassis”) which permits it to be used by heel, mid-foot or forefoot strikers.
Pearl Izumi may have invented the seamless upper and it’s immediately clear that the Road N1 possesses an excellent fit. The shoe holds on snugly to the entire foot and especially so to the top of the foot, yet it is anything but uncomfortable. The toe box is relatively low but it never rubs on the toes.
This shoe has a nicely padded heel counter and there’s an efficient lacing system which is slightly off-center. The manufacturer’s attention to detail is reflected in the simple fact that the shoe’s laces are neither too long nor too short. They’re just right!
Initially, as you hold on to the Road N1 and test its flexibility, it feels a bit stiff. But this is not a problem on roads; it feels flexible enough in action.
When you first walk in this shoe, it feels like you’re on top of an air cushion, nice and soft. Interestingly, there’s been some debate and confusion about the feel of the shoe on the run. Pearl Izumi states that its midsole “promotes a smooth and quick running sensation,” which is referenced elsewhere as an “ultra-smooth” ride. But one retailer’s website states that the shoe has minimal cushioning and a “semi-firm” ride. Which is it? I’d say the answer lies somewhere in the middle. I view the Road N1 as delivering a cushioned firm ride on a par with the feel of the Mizuno Wave Rider 16 running shoe. Cushioned but firm is not a bad thing. In fact, it may offer the best of both worlds to a large number of runners.
I think that Pearl Izumi is correct when it highlights the shoe’s quick running sensation. When jogging on a crushed gravel trail, I felt I could run at a quick pace, especially because the midsole is highly, unexpectedly protective. Even though the Road N1 has no dedicated heel pad, the cushioning at its rear is mid-range, not too firm or too soft.
The Road N1 produces an agile and pleasingly bouncy ride on a hard-packed dirt trail; it allows the runner to move confidently, even as the trail twists and turns. The shoe is just competent on a natural trail since the sleek, flat sole cannot generate much grip.
This product also feels fast on urban and suburban sidewalks. Forefoot runners will find that they can get on their toes in this shoe, taking advantage of the blown rubber outsole. What’s surprising about the N1 is that it possesses a good deal of inherent stability, more than one would expect from an “N” (neutral) series model. There’s a yellow colored support bar built into the outsole which works well.
On asphalt, it delivers a steady-paced, relaxing journey. This translates into a good choice for a race day 5K to half marathon shoe. One caution about the shoe is that it should not be used on rainy days, as the flat sole will produce a slippery ride.
The Road N1’s quick but shielding suspension makes it a natural choice for running training laps on a crushed gravel track.
Verdict: With the Road N1, Pearl Izumi has produced a shoe that’s light, fast and protective. It should serve quite well as a daily trainer for mid-foot and heel strikers. Some fleet-footed runners may place it at or near the top of their rotation when it comes to the shoes they wear on critical training days.
