How to Choose Trail Running Shoes
Picking a trail running shoe comes down to four things: how aggressive the lugs need to be, how much protection you want underfoot, how much cushion fits the distances you run, and whether the shoe fits your foot. This guide walks each of those, names the trail shoes we actually carry at Grivet, and answers the questions we hear most often.

1. Match the shoe to the terrain
Trail shoes are built for specific surfaces. The wrong shoe on the wrong trail makes a great run miserable.
Door-to-trail and gravel. Greenways, packed dirt, gravel paths, and the road sections you run to get to the trail. Look for a shoe with shallow 2-3mm lugs and decent road manners. The Hoka Challenger 8 is the cleanest example.
Standard singletrack. Most non-technical trails: rolling, packed or moderately loose dirt, occasional roots. A 4-5mm lug works well. The Hoka Speedgoat 6 and Brooks Cascadia 19 both fall here.
Technical and wet. Mud, wet rock, steep descents, scree fields. You want 5-6mm lugs and a sticky rubber compound. The Saucony Peregrine 15 is the workhorse pick at this end of the spectrum.
Ultra and long days. Long-mileage trail running rewards cushion and a comfortable upper. The Speedgoat 6 covers most ultra runners well; the Altra Lone Peak 9 is the cult zero-drop pick for thru-hikers and ultra runners who already prefer that platform.
2. Lug depth and outsole grip
Lugs are the rubber knobs on the bottom of a trail shoe. Lug depth is measured in millimeters, and it dictates what surfaces the shoe handles well.
2-3mm lugs. Hybrid territory. Works on packed singletrack, gravel, and some road. Doesn't bite well in mud. Best for runners who mix surfaces.
4-5mm lugs. The sweet spot for most trail runners. Bites well on dirt, handles light mud, doesn't feel terrible on the gravel access road back to the trailhead.
5-6mm lugs. Aggressive. Built for mud, soft ground, and technical terrain. The trade-off is slower, less comfortable feel on hard surfaces.
Outsole compound matters as much as lug depth. Vibram Megagrip is the gold standard for sticky rubber on wet rock. Most current Hoka, Saucony, and Brooks trail shoes use it.
3. Rock plates and underfoot protection
A rock plate is a thin layer of stiffer material (often TPU) sandwiched in the midsole that keeps stones and roots from being a problem under your foot. Without one, every sharp object you step on transmits straight to your foot. With one, you barely notice.
Almost every modern trail shoe has some form of rock protection. Higher-stack shoes like the Hoka Speedgoat protect by virtue of foam thickness alone. Lower-stack shoes like the Saucony Peregrine use an explicit rock plate. If you run rocky terrain, prioritize protection. If you run smooth singletrack, it matters less.
4. Stack height and cushion
Stack height is the total foam under your foot. Trail shoes range from low-stack (under 25mm) to max-cushion (35mm+).
Low-stack trail shoes like the Saucony Peregrine 15 (28mm) and Altra Lone Peak 9 (25mm) give you ground feel and stability on technical descents. The trade-off is fatigue on long runs and less comfort on hard impacts.
Mid-stack (28-32mm) covers most trail running well. The Brooks Cascadia 19 sits here.
High-stack (33mm+) shoes like the Hoka Speedgoat 6 (40mm) protect you on long, all-day efforts but feel tippy on technical descents and rocky scrambles.
5. Waterproof or not
Most trail shoes come in two versions: standard mesh and Gore-Tex (GTX). Both have legitimate use cases.
Standard mesh. Drains water out as fast as it lets it in. Best for warm weather, summer running, and any trail with creek crossings. Feet get wet, then dry quickly.
Gore-Tex (GTX). Keeps water out. Until water gets in, then it traps it. Best for cold weather, snow, and shoulder-season runs where you want feet warm and dry. Also runs hotter in summer.
If you only own one pair of trail shoes, get the standard mesh version. Pick GTX as your second pair if you run year-round in a wet or cold climate.
6. How a trail shoe should fit
Trail shoes need a slightly different fit than road shoes:
- A bit more room in the toebox. On long descents your foot slides forward. Half a thumb's width of toe room is right.
- Locked-in heel. Heel slip on technical terrain causes blisters and can roll an ankle.
- Snug midfoot. Side-hill running puts lateral force on the foot. The shoe should hold without pinching.
- Account for swelling. Feet swell more on long trail efforts than on equivalent road miles. Size with this in mind.

FAQ
Can I use trail shoes for road running?
You can, but you shouldn't make it a habit. Lugs wear faster on pavement and don't transfer power as well as road foam. If half your weekly miles are road, get a road shoe and use the trail shoe for trails only.
How long do trail shoes last?
250-400 miles for most trail shoes. Lugs are the limiting factor. When the rubber rounds off and the lug edges go soft, traction drops noticeably. Mileage drops faster on rocky or abrasive terrain.
Do I need a different size in trail shoes vs road shoes?
Usually the same size, sometimes a half size up. Long descents push the foot forward in the shoe, so a tiny bit of extra room in front prevents toenail trauma. We'll check at fit.
What about ankle support? Should I get a mid-cut trail shoe?
Most trail running shoes are low-cut and that's fine for the vast majority of trail runners. Strong ankles come from running on uneven ground, not from shoe collars. If you've sprained a lot or you're doing technical scrambling with a pack, a mid-cut hiker is reasonable.
Are trail shoes good for hiking?
For day hikes up to 8-10 miles on dry trails, yes. Many through-hikers prefer trail runners over boots because they're lighter and dry faster. For wet, rocky, or pack-loaded backpacking, a hiker with more torsional stiffness is the better tool.
Do you carry waterproof trail shoes?
Yes. Gore-Tex versions of the Speedgoat, Peregrine, and Lone Peak are typically in stock. Worth knowing: GTX shoes keep water out until water gets in, then they hold it. Pick GTX for cold-weather running, not for summer.
