Updated 2026-08-14 Researched, not tested in person
Quick answer

The Altra Lone Peak 9 Trail Running Shoes has a published weight of 21 oz per pair and a listed price of $100.96, which is about 13 percent of a 10 lb ultralight base weight.

The Altra Lone Peak 9 Trail Running Shoes is our beginner tier pick in trail shoes, with a published weight of 21 oz per pair and a listed price of $100.96. The most common shoe on the long trails, on a zero drop platform with a wide toe box that suits feet which have swollen half a size by mile eighteen. Zero drop loads the calf and achilles differently, so transition over weeks.

What is the Altra Lone Peak 9 Trail Running Shoes actually good at?

The most common shoe on the long trails, on a zero drop platform with a wide toe box that suits feet which have swollen half a size by mile eighteen. Zero drop loads the calf and achilles differently, so transition over weeks.

Best for: Wide feet, long days, and anyone whose toes go numb in a normal shoe.

Weight on your feet costs several times what the same weight costs in your pack, which is the whole argument for trail runners over boots once your base weight is low enough that ankle support is not doing much.

What does it do to your base weight?

At 21 oz per pair this item accounts for roughly 13 percent of a 10 lb ultralight base weight and about 7 percent of a 20 lb traditional one. That framing matters more than the raw number: an ounce saved on a headlamp is noise, and a pound saved on a shelter is a category of its own. Put your real figures into the gear list builder and the same item will show you what it costs against your list rather than against an average one.

Published weights are taken in the manufacturer's favour: usually the smallest size, usually without the stuff sack, stakes or guylines that come in the box. Expect a real-world figure an ounce or two heavier and weigh it once when it arrives. A $9 kitchen scale is the cheapest useful upgrade to any gear list, because it stops the spreadsheet lying to you.

How does it compare with the rest of the trail shoes?

Every item below has been verified against the retailer listing, and every weight is the manufacturer's published figure for the configuration named. Sorted lightest first, so the trade between weight and everything else is visible in one pass.

ModelPublished weightListed price TierWhere to buy
Altra Lone Peak 9 Trail Running Shoes 21 oz per pair $100.96 Beginner Backcountry, Amazon
HOKA Speedgoat 6 About 21 oz per pair Varies Intermediate Backcountry, Amazon
Brooks Cascadia 18 About 22 oz per pair Varies Expert Backcountry, Amazon

Heavier but more capable: Brooks Cascadia 18 at About 22 oz per pair. Weight alone never decides this. The lightest option in a category is usually the one with the narrowest window of conditions it works in, which is exactly the trade the roundup spells out tier by tier.

Why weight on the feet costs more

Weight carried on the feet costs several times what the same weight costs in the pack, because you lift and swing it with every step rather than carrying it passively. That is the entire argument for trail runners over boots once your base weight is low enough that ankle support is not doing much work. Published pair weights are for one reference size that is probably not yours, and feet swell on long days, so most long distance hikers size up half a size or more. Expect to replace trail shoes every 400 to 500 miles, at the point the midsole dies rather than when the upper tears.

Which complete kits use it?

This item appears in 5 of the complete gear lists on this site, which is the most useful context a single product page can give you: not what it weighs in isolation, but what share of a finished kit it accounts for and what the rest of that kit looks like around it.

Complete kitSeason Kit base weightThis item Share of baseKit cost
Sub-10 lb Three season 8 lb 11.9 oz 21.0 oz 15% $3121.78
Thru-hike Three season, long distance 9 lb 15.2 oz 21.0 oz 13% $2700.83
Desert Desert, spring and autumn, high heat 11 lb 4.5 oz 21.0 oz 12% $2902.86
Sub-15 lb Three season 13 lb 3.1 oz 21.0 oz 10% $3054.16
Budget 3-season Three season 14 lb 15.7 oz 21.0 oz 9% $1209.25

Every one of those kits lists every item you need to actually go, with a per item weight and price, a running total down both columns, a section on what you can skip, and an upgrade ladder priced in grams saved per dollar. Each also loads straight into the gear list builder so you can swap this item for something you already own and watch the total move. That is usually a faster way to decide whether a purchase is worth it than reading another review of it.

Who should skip it?

Anyone who already knows they will keep doing this. Beginner tier gear works correctly and costs a fraction of the alternatives, and that is exactly the right trade for a first season. It is the wrong trade if you already know your base weight target and this item is the thing standing between you and it.

Going lighter must not mean going unprepared. Shelter adequate to the actual conditions, insulation, rain protection, water treatment and a way to call for help are fixed costs on any list. If a lighter version of this item means cutting into one of those, it is the wrong purchase however good the spec sheet looks. You are responsible for what you walk into, and the forecast is not the conditions.

Is the Altra Lone Peak 9 Trail Running Shoes worth the money?

Where can you buy the Altra Lone Peak 9 Trail Running Shoes?

Backcountry carries this category and is the first link on this page, because it is where this audience shops and it pays us a higher commission than Amazon does. Amazon is the second button. Stock and pricing differ between the two often enough that checking both is worth the extra thirty seconds.

What does the Altra Lone Peak 9 Trail Running Shoes compete against?

On the same shelf: HOKA Speedgoat 6, Brooks Cascadia 18. The comparison table on this page lines them up by published weight and price so the trade is visible rather than argued. Our full ranking of the category, split into beginner, intermediate and expert tiers, is in the roundup linked below.

Are the weights on this page measured or published?

Published. We compare manufacturer specifications and verified owner reviews, and we do not test gear in person or run a gear lab. Manufacturer weights are usually taken from the lightest size, without stuff sacks, stakes or guylines, so a real-world figure is often an ounce or two heavier. Weigh your own kit and put the real numbers into the gear list builder.

How we choose: we compare published manufacturer specifications, listed weights, and verified owner reviews across retailers. We do not test gear in person, and every weight quoted here is the manufacturer's figure unless we say otherwise, so weigh your own kit before you trust a total. Going lighter also means carrying less margin, so treat insulation, navigation, water treatment and an emergency plan as fixed costs rather than places to save grams.
