Merrell Thermo

Where do you plan to run?

• Road or track: Lighter shoes for speed, more cushioned shoes for distance
• Gravel paths: Hybrid shoes, designed for both road and trail

Cushion comes down to "feel" vs. "float"

• Minimal and barefoot cushioning: little to no padding, more groundfeel
• Moderate cushioning: more traditional ride
• Maximum cushioning: softest, bounciest ride

What kind of support do you need?
Depending on your gait, you may need a stability shoe. But most runners will fare well with a neutral shoe.

Make sure the shoe fits.
No breaking in periods, period! Your shoe should fit well from the get go.

How long will you be on the trail?

• Hiking shoes: day hikes or ultralight backpacking
• Hiking boots: multiday treks with heavier loads
  

What upper is right for you?

• Leather: water- and abrasion-resistant, durable
• Synthetic: lightweight, break in easily, dry faster
  

Look at the lugs

• Deep, thick lugs improve grip
• Wider lug spaces sheds mud and offer good traction

Check crampon compatability
Mountaineering and winter hiking may call for crampons. Narrow your search for boots with crampon compatibility.
