Our Verdict

Lightweight performance over rocky, wet, and dry trails is a purpose the Nike Terra Kiger 6 will satiate. This trail runner is light and comfortable, keeping you moving while the miles accumulate. The upper is breathable while the rock-plate infused midsole is protective from underfoot hazards. This shoe will fit women of all sizes. The forefoot platform is a little wide but will do best for women with medium to narrow feet. It's 4-mm drop, and low stack height makes it quite stable, offering balance while you barrel down steeps. If you decide to purchase this sleek and lightweight trail runner, but sure to size up a half size as it runs a little small.

Our Analysis and Test Results

The Nike Trail Terra Kiger 6 stands out for its lightweight design that is built to take on wet, rocky terrain. Designed for short to medium distances, it's an excellent choice race days. The uppers are breathable but lack protection from tiny particulates. It also runs about a half size small, so be sure to size up, especially if you plan on running ultra distances.

Performance Comparison


The Nike Terra Kiger is a favorite amongst women that fit it well. It's lightweight with super sticky rubber that'll grab most trail surfaces. It runs a little small and doesn't do great in mud  but for everything else  it's a wonderful choice.

Foot Protection


Packed with 14.5mm of cushioning in the heel and 10.5mm of cushioning in the forefoot, your feet will be protected from most underfoot hazards. It comes complete with a segmented rock plate that does work to keep your feet from feeling the stabs of underfoot hazards.

The toe cap is well reinforced and provides some protection from toe stubs on the trail.

While the upper offers excellent breathability and dries out quickly, it captures debris between the upper layers. We experienced this while running through sandy conditions, causing us to empty our shoes constantly. However, if you're just running over dirt, rock, or grass, this trail runner will provide all the protection you need.

The cushioning is minimal but protective. While the upper is quite breathable  small debris can get caught between the two layers  which is annoying on sandy or clay trails.

Sensitivity


This shoe boasts a high level of sensitivity. While the midsole has air cushioning, it's thin enough to feel the undulations of the trail. Feel stable, in control, and confident while treading over treacherous terrain.

This shoe is flexible and quite sensitive. You'll feel rocks underfoot while the outer molds to engulf them and provide stability as you head downhill.

Traction


We really love the outsole that does an excellent job sticking to rocky terrain. We used this shoe while scrambling up gneiss ridges, and it performed wonderfully.

The traction pattern sports smaller lugs are that incredibly sticky. We found this outsole works best on rocky trails  dirt roads  single track. It doesn't perform well in mud unfortunately.
The traction pattern sports smaller lugs are that incredibly sticky. We found this outsole works best on rocky trails, dirt roads, single track. It doesn't perform well in mud unfortunately.

Since the lugs aren't very long or aggressive, it also performs well on the road. Unfortunately, when testing on super muddy trails, the lugs didn't shed the mud well, and we were left with a tractionless shoe for miles. It performs impeccably over hard-packed snow but struggles when the snow is deep and soft. Overall, traction scores "good" on our scale, as many other shoes in this review also feature this kind of traction. Don't be afraid to use it while tacking technical terrain or hiking off-trail. It'll perform well.

After running on a rainy day  our tread pattern looked like this after just five minutes of running on clay. Unfortunately  it didn't shed mud the whole time  weighing us down. Not recommended for wet and muddy conditions.

Stability


The lower stack height and relatively wide forefoot make this trail runner very stable. It doesn't have any additional stability elements. The outsole around the heel has material that splays out around its base, which adds more lateral stability upon heel impact (if you're a heel striker).

The outsole around the cup of the heel flairs out  offering stability  especially on steep descents where you might find yourself leaned way back.

The forefoot, with its low height and wide platform, allows your toes to spread out, which inherently offers better balance. The cushioning underfoot is super airy and perpetuates your forward with every step, while keeping your foot low to the ground. The shoe itself is quite flexible and supportive. Overall, we had no issues with rolled ankles, even though our main tester is renowned for it.

Comfort and Fit


When you get the right size, this shoe fits really nicely. We ordered a size nine and felt the shoe was just a touch too small. Other online users verify this observation, so we recommend sizing up a half size, especially if you use thicker socks.

The collar is thin and offers just the right amount of padding. The body of the shoe is a bit shallow  so if your foot is voluminous  you might find the fit a bit tight. If you're blessed with narrow and thin feet  this shoe will fit nicely.

The overall comfort is stellar. A combination of the airy yet stiff cushioning, padded tongue, and a supportive collar around the Achilles makes for a comfortable ride, whether you're running one or 20 miles. It also comes with a convenient pull-on loop at the back, meaning you can clip this shoe to a backpack if needed.

The tongue is soft  thin  and padded  which adds additional comfort. There's no chaffing or weird pinch points that we noticed in this shoe.

We also appreciate the breathable upper, which makes it suitable for both winter and hot summer running. The fit of the shoe runs 'regular'. The toe box will fit those with a wide foot, but it is best for those regular to narrow feet. The toe box tapers to the top, which isn't the best for downhills. After 10 miles, we felt our feet getting hot, and on the downhill, our toes felt a bit squished. Our toes rubbed together, causing a tiny blister to form. There is also a smidgen of arch support, but its a neutral fit.

The airy cushioning underfoot makes running mile after mile comfortable and "springy". On speed workouts  this is the shoe we reached for.

Weight


Weighing only 8.7-oz (size nine), this proves to be a superlight shoe, one of the lightest tested. If you're seeking a trail shoe that doesn't hinder your stride and cadence, this is one to consider.

Value


This shoe has a price tag that is congruent with most trail runners in this review. If you're a lady seeking a low profile, lightweight trail shoe that doesn't need an aggressive traction pattern, then this is seriously one to consider. After putting 60 miles on it, it shows very little wear and tear. Past models that we've tested have seen upwards of 200+ miles of wear. After this period of wear, we noticed the cushioning breaking in, with some wear to the collar. The collar has been updated with this model, which could improve durability. However, we'd assume it'll have similar longevity as previous models as it uses the same materials.

If you're seeking a trail runner that'll easily transition from roads to singletrack  this is one to consider. The price is just right. Feel confident on uneven terrain and crush both technical and non-technical surfaces with a spring in your step. Don't buy this shoe is you encounter muddy conditions often.

Conclusion


If you're seeking a light and fast trail runner that can easily transition from the road to the trail, the Nike Terra Kiger 6 is one to consider. Its breathable, light, comfortable, and comes with air cushioning underfoot to keep you comfortable mile after mile. This isn't our first choice for ultra distances, but we've seen many women sport them with success. If you do purchase it, be sure to size up a half size, especially if your feet swell when you run.
