Xero’s Z-Trail is a minimalist sandal in a number…

Xero’s Z-Trail is a minimalist sandal in a number of ways. The sole and midsole together are less than a centimeter thick, with no thick heel or arch support. They secure your feet with a hook and loop heel strap and a continuous polyester strap that you pull to tighten.
They are unexpectedly good at protecting the soles of your feet for such a light and flexible sandal, and traction is very good to excellent. Lateral support is an issue, though, and you can definitely feel roots and sharp rocks under your feet. A great choice for someone looking for a well-made and conceived minimal sandal.
- Feel almost weightless
- Great feel for the ground
- Nice wet and dry traction
- Comfortable strapping
- Harder sole sections give some protection
- Well made for such a light shoe, should be quite durable
- Lateral stability is good but not great
- Sole protection is limited
- People who want thick heels or arch support should look elsewhere
Initial Impressions and Fitting
The pair I received fit my feet well and weighed in at about 10 ounces—for the pair! For the sake of comparison, that is less than half as much as a pair of Chaco sandals and slightly less than a pair of Vibram Fivefingers I tested a number of years ago.
They are extremely flexible. The sole/midsole is made of two different materials—the medium brown part is stiffer but less grippy than the black sole pieces. Between the sole, midsole, and softer topsole, they are less than a centimeter thick.
I took this photo to compare the thickness of the Xero Z-Trail sole to a pair of Chacos.

The straps are smooth polyester—low friction. The straps on mine are brown and black with a pattern, reasonably good-looking. When you initially put them on, adjust the heel strap (it secures with hook/loop) and forget about it. Then, slide the front strap through the rubber piece on the outside of your forefoot to get the fit right.
To take them on and off, you loosen and tighten the strap as it runs through a friction clip on the outside of your ankle. Chaco wearers will recognize the positioning of the straps—though the hardwear is a little different, the basic layout looks like a Chaco Z/1. When you tighten the shoe, there is a small rubber ring you can use to make sure the loose end doesn’t flap around.
How They Fit and Feel
The continuous front strap is pretty easy to adjust on the fly, and you can strap your forefoot down so it feels tight and secure if you are on uneven terrain. Likewise, you can pull the strap tight and lock your heel down. The heel part feels very secure, both forward and back and side to side. The forefoot slides around a little, even if you pull them very tight.
If you are hiking on steeper or more uneven trails, you will feel your feet moving laterally at times. The straps, despite a lot of walking and hiking, never blistered my feet. Chaco wearers will appreciate the strap layout that is similar, but these straps are both more narrow and a softer-feeling polyester webbing. There is no break-in time on these shoes.
When you walk and hike in these shoes, you can clearly tell that you do not have arch support or a thickly padded or shielded sole. Your feet get a very good sense for the ground in these. If you are interested in minimal sandals but have not worn them much or at all, you may need to ‘break in’ your legs and feet.
I suggest you get used to these gradually. Wear them for an hour or two, a day or two a week, and increase how often and how long you wear them. How long should that process last? That depends on your individual comfort level, I think. It took me a number of weeks to get used to minimal shoes at first because I have extremely flat feet. Because I have been wearing Fivefingers shoes for a number of years, I was quickly wearing Xero’s Z-Trail for hours a day on warmer weekends.
One thing I have particularly grown to like is that the material immediately under your feet is soft-feeling and comfortable. It is one of the reasons I find myself reaching for these repeatedly as the weather warms up.
The Z-Trail has very good traction. They are not the best, but they are better than most. The black sections of the sole are made from a grippy rubber that does not slip much, if at all, on rocks. I wore these on a series of riverside hikes and got them in the water. They did very well on slimy rocks and in mud, except if you step hard on the less-grippy brown sections, which have a tendency to slip a little on wet rocks.
Having a thin sole enhances traction somewhat, because feeling like you are barefoot helps with traction. The only real limit I encountered was on gravelly downhills and wet leaves, where the relatively shallow sole lugs did not work as well as, say, the more aggressive soles on day hiking shoes or hiking boots.
The ‘midsole,’ the light brown part, is a little bit more stiff and provides a measure of buffer between your feet and the sometimes hard or sharp roots or rocks on trails. On the harder and more rugged trails, I felt those obstacles at times. If I plan to be on consistently rough or abrasive trails, I don’t reach for these or any other minimal shoe.
This is a little hard to assess because minimal shoes aren’t my favorite choice for walking on hard pavement. I wore the Z-Trails on dirt and rock trails over the course of a few months, 40-50 miles, and they have relatively minimal wear. I had a slight tendency to skim the toe against rocks, which scraped the softer topsole a little.
The Testing Grounds
I wore these sandals on a series of local hikes over about sixty days—the Billy Goat trails by the Potomac River, Sugarloaf Mountain, the Cabin John trail near my house, and the C&O Canal tow path. I also regularly wore them while walking the dog, hanging around on weekends, walking the sidelines of high school sporting events, and doing yard work.
I would not normally wear a minimal shoe on the most aggressive section of the Billy Goat trail but tried these out to test their limits on a steeper and more rocky trail. I was in and out of the Potomac River and a stream alongside another local trail. I walked about forty to fifty miles in them over the course of the testing.
I did not hike these with any heavy backpacks but regularly carried twenty pounds or more. At those light weights, I don’t feel the need for much support, and hiking with twenty to twenty five pounds on my back in these sandals felt great.
- These strike a decent balance—a minimal sandal with just enough protection to appeal to a wider audience.
- The sandals are made to last and should be very durable for such a light shoe.
- Good job on the tread pattern and materials.
- Minimal shoes have limits. In addition to employing a sole that is not very suitable for rough conditions, these have just fair to good lateral forefoot support.
- I like wearing them. During the Thanksgiving week on my parents' chilly wood floors in New England, I wore these as my slippers and on shorter walks with wool Injinji toe socks. Sandals this light might also end up being a serious contender for post-hike summer evenings. As the weather has grown warmer this spring, I find myself reaching for these as a lighter-weight option to the Chacos I often wear.
If minimalist is your thing these are a good offering.

If minimalist is your thing these are a good offering. Having run more than 200 miles in them and used them for day-to-day wear in between they have been robust and are very light.
- Well made
- Very good customer service
- No instep or overly thick soles
- No toe post, so toeing down a hill in wet mud is difficult
- Sizing can be on the small size, beware when ordering
- Made in China
I run in sandals and have used a mixture, over time, to include Luna and Earth Runner sandals. These are a slightly different take in that they use an over strap in the front of the sandal so are very nice for those people who don't like things between their toes.
Light on the foot they are very hard wearing, but don't expect a big tread as they use a lightly treaded sole. That said I have run in the rain and on a multitude of trails in them and love the open air feel on your feet when you do. What I really like is that they work for just about any activity from water sports (not kayaking as the heels will rub on the boat bottom when paddling) to trail running. With a little wipe down you can then wear them to a summer party straight after.
The straps have improved over time so now are nicely coloured and comfortable to wear. Easy to adjust and secure as far as a sandal goes. It is not a fully enclosed shoe so will not have the same foot security as one does, but then it's a sandal!
In the wet expect a quick dry out and actually a surprising amount of grip from the rubber of the fit bed on the sole of your foot. Only thing that defeats that in reality is liquid mud on them. I only had issues once on a 35-mile run when I had to go down hill in them through a very muddy field. I took them off then put them back on at the bottom—easy really!
They pack very small, weigh very little, and as I was given a review pair in 2016 and I am still running in it. They are actually very hard wearing. For the price it's a hard one to beat.

I tried these on a couple of hikes, for use as a camp shoe, for swimming and creek crossing, etc. But I soon gave up on them, not just due to the poor sole protection and the lateral movement that were cited, but also due to dirt and gravel quickly getting into the sandals (drier conditions) and water (wetter conditions).
- Super lightweight
- Decent design and construction for the weight
- Not sturdy enough for most people
- Does not keep out debris very well
The lightweight simply wasn't worth it to me.
I recommend something sturdier unless you have ideal trail conditions and feet that can handle the stress.
Try "Gold Pigeon" sandals, model 5931. I'm very happy with them after a year's usage. Much sturdier and not much heavier (14 oz for my EU 44 pair). Name brand U.S. sandals can be excellent but often weigh twice as much (I'm a PCT hiker).
