Salomon S-Lab Sense Ultra
Something very right is happening at design center in Annecy, France. For the second season in a row, the company鈥檚 bright red trail shoes have blown away the competition. The Sense Ultra is everything a front-of-the-pack trail shoe should be鈥攅xtremely fast, secure, nimble, and stable in the rough. It also has cojones. Despite weighing a mere 7.6 ounces, it sports a thick enough midsole (13-millimeter heel and nine-millimeter forefoot) to take steep, rock-strewn terrain at full speed. It鈥檚 pricey, and the slim racing fit might squeeze wider feet (especially on foot-swelling marathons), but there is simply no shoe on the market built better for flying over any and all terrain. 7.6 oz; 4 mm drop

Inov-8 Roclite 243 Trail Running Shoe

BEST FOR: Racing, midfoot runners, narrow feet.
THE TEST: The with fangs. There is very little shoe underfoot (just six millimeters up front and a nine-millimeter heel), and what鈥檚 there is a Gumby-like invertebrate鈥攜ou can bend any part of the sole in any direction. That flexibility, combined with an extremely secure midfoot and reasonably secure heel (there鈥檚 no external heel counter), made it the most agile and efficient shoe here. It鈥檚 an ideal racer on flowy trails, though most testers needed to ease off the gas when the turf got more technical.
THE VERDICT: On rolling trails, they flat-out scream. But they probably don鈥檛 have enough guts to be your everyday driver on loose, rocky trails. High-volume feet, steer clear. 8 oz; 3 mm drop

AGILITY: 4.5
The North Face Hyper-Track Guide Trail Running Shoe

BEST FOR: Going fast on flat terrain.
THE TEST:聽The is hard to pin down. It鈥檚 one of the new tweener shoes鈥攍ightweight with moderate heel drop鈥攖hat both midfoot and mildly heel-striking testers liked. With lugs so flat they almost don鈥檛 exist, the shoe delivers a smooth stride on firm dirt and pavement. 鈥淎 great choice for dust paths or smooth singletrack,鈥 said one tester. On road, however, some felt it was too spartan and firm to log a lot of miles. That low-riding firmness, though, translates to a lot of speed and energy, and great agility on technical trails.
THE VERDICT: A jack-of-all-terrains, with a slightly more minimalist approach than the comparable Montrail Fluid Feel. Keep it far away from mud. 9.7 oz; 8 mm drop

La Sportiva Helios Trail Runnng Shoe

BEST FOR:聽Long runs in the hills.
THE TEST: Return of the champ! This shoe is so similar to Sportiva鈥檚 acclaimed Vertical K from last year that a tester wore one of each at the same time and could barely tell the difference. Sportiva took the flexy, wavy midsole of the Vertical K and鈥攄itching the integrated gaiter and giving you access to the laces all the way down for better micromanagement of the fit. The vibe is still very low and natural, and the outsole鈥檚 fat foam ridges provide a fair bit of cushion without feeling soft or disconnected from the ground.
THE VERDICT: Our favorite shoe for guys with consistent, midfoot-striking form who want a really natural-feeling, slipper-like fit without getting all caveman about it. 8.1 oz; 4 mm drop

Ecco Krypton Trail Running Shoe

BEST FOR: Big feet, mellow trails, midfoot strikers.
THE TEST: We鈥檝e found previous Ecco trail runners to be a bit clunky, but several testers raved about the fit of the new Krypton鈥 that remains stoutly protective on rocky trails, thanks to a thick, stiff rubber outsole. The Krypton has a noticeably roomy last鈥攚ide at both forefoot and heel鈥攚hich means that this shoe will feel most secure on high-volume feet. The downside? All that extra room made the shoe a little sloshy on off-camber terrain, and the stubbornly hard-to-adjust laces didn鈥檛 help.
THE VERDICT: The roomiest shoe here. It felt best on flat trails, but some testers found it too stiff. 11.2 oz; 8 mm drop
COMFORT: 3.5鈥
PROTECTION: 3
New Balance Leadville 1210 Trail Running Shoe

BEST FOR: Comfort addicts, high-volume (and swollen) feet.
THE TEST: This shoe may be named for one of the nastiest ultra races out there, but it鈥檚 intended to be . 鈥淭he most comfortable trail runner I鈥檝e worn in years,鈥 said one tester. With pillowy heel padding, a giant, soft midsole, a squishy foam tongue, a high-volume fit, and stretchy, weblike overlays (rather than stout bands), this shoe goes overboard to pamper the feet of those logging mega mileage. Even more amazing is that all those accommodations don鈥檛 come with a weight penalty, though this is the least agile shoe here, and most testers found it a touch sluggish.
THE VERDICT:聽A La-Z-Boy for hardworking feet. 10.3 oz; 8 mm drop
COMFORT: 5鈥
PROTECTION: 4.5
Montrail FluidFeel Trai Running Shoe

BEST FOR: Road and trail.
THE TEST: The . With a thick mattress of firm foam and recessed lugs, it felt smooth on pavement, but the narrow, snug midfoot made it noticeably secure on real-deal trails, including the steepest, most hazard-littered ones we could find. Naturally, a shoe with this breadth requires some sacrifices鈥攜ou鈥檒l lose a little comfort on the road and a little agility on technical terrain, but far less than with most hybrid shoes. Watch your step: that plastic arch support is slippery on logs.
THE VERDICT:聽A true off-roader that doesn鈥檛 feel clunky on pavement and has a bit more pillow and bite than the other hybrid here, the North Face Hyper-Track. 9.7 oz; 8 mm drop
COMFORT: 4鈥
PROTECTION: 4.5
