How to Choose Hiking Shoes | Fit, Terrain & Pack Weight

Choose hiking shoes by matching them to terrain, pack weight, and hike length — then prioritize fit and break-in over brand or price.

Picking the wrong pair turns a good trail into a miserable one, and the biggest mistake is starting with looks instead of the ground you’ll cover. The right approach starts with where you’ll hike, how heavy your pack is, and how far you’ll carry it. REI’s guidance on choosing hiking boots is built around that same order — terrain first, then load, then fit. When you line those up, the shoe choice narrows itself.

Match The Shoe To Terrain And Pack Weight

The trail type decides the shoe category more than anything else. On smooth, well-maintained paths, a lightweight trail shoe or hiking shoe handles the job. On rocky, uneven ground, you want more support underfoot. Steeper, rougher terrain with talus or loose scree pushes you toward a boot with a stiffer sole and higher ankle cut.

Pack weight shifts the decision too. REI’s guidance says light hiking boots are worth considering when your pack runs over 35 pounds, and heavy hiking boots make sense once you’re carrying more than 40 pounds. Day hikers with a light load rarely need that much ankle support; overnight trekkers with a full pack usually do.

Heavier boots generally add support and protection, but they’re less practical for day hikes and may take longer to break in. If your hikes are short and your pack is light, a heavy boot is overkill. If your route is rough and your load is heavy, a flimsy shoe is a mistake. Match the tool to the job.

How Should Hiking Shoes Fit?

Fit beats every other factor, and REI recommends having your foot length, width, and arch length measured at an REI Co-op store. Street-shoe size is a weak starting point; measured fit is what actually works on the trail.

Salomon’s guidance on choosing hiking shoes covers the practical details. Try shoes on at the end of the day, wear the hiking socks you’ll actually hike in, and leave room for swelling — when you’re between sizes, take the bigger one.

The shoe should feel snug without side-to-side movement. If your heel lifts or your toes strike the front on an incline, adjust the lacing or size up. If you use custom insoles or orthotics, bring them when you try shoes on — they change the fit, and you need to know that before you buy.

Break-In And Common Mistakes To Avoid

New hiking shoes need a break-in period, and skipping it causes most first-trip blisters. Salomon’s advice is to start by wearing them around the house, then progress to short walks and short hikes before your real outing. A shoe that fits well still needs time to mold to your foot.

The most common mistakes people make are all avoidable:

• Buying without thinking about terrain and pack weight
• Trying shoes on in the morning, when feet are smallest
• Fitting with casual socks instead of hiking socks
• Ignoring heel lift or toe strike on inclines
• Skipping the break-in entirely
• Choosing by street-shoe size instead of measured fit

You can do your foot a favor before you even shop. Measure your feet properly, figure out what terrain you’ll actually hike, and know your pack weight. When you’re ready to buy, a good fit and a short break-in beat a big brand name every time.

FAQs

Should I buy hiking shoes a half size bigger?

Generally, yes. Your feet swell during a hike, and you need a thumb’s width of space at the toe to prevent bruising and blisters on descents. When you’re between sizes, Salomon advises taking the bigger size. Try on shoes at the end of the day, when your feet are at their largest, and wear the socks you’ll hike in.

Are hiking shoes or boots better for beginners?

Start with hiking shoes if your terrain is moderate and your pack is light. They’re lighter, need less break-in, and work well for day hikes. Move to boots when your pack goes over 35 pounds or your trail gets rocky and uneven. Beginners on casual trails will find shoes more comfortable out of the box.

How many miles does it take to break in hiking shoes?

There’s no set number, but the process is gradual. Start with short walks and easy hikes to let your feet adapt. Watch for hot spots — if a shoe rubs the same spot every time, that’s a fit problem, not a break-in problem. Most well-fitting shoes feel comfortable within a few short hikes.
