Thick, well-cushioned socks are one of the most underrated pieces of travel and hiking gear. They help prevent blisters, provide extra comfort on long days of walking, and offer thermal protection when temperatures drop. When you’re covering big miles or exploring cities on foot, the right pair of thick socks can make all the difference.
After researching top-rated options available on Amazon, I’ve selected five thick sock pairs that balance comfort, performance, and durability — all ones I’d confidently wear on my own trips.

Personal Note
I’ve personally tried both Smartwool and Icebreaker hiking socks during my backpacking trips and long walks. Both brands are extremely comfortable and reliable, but they shine in different conditions.
Icebreaker socks are my go-to choice for hot weather — they’re highly breathable and help keep my feet cool and dry, even after hours of walking. On the other hand, Smartwool socks are slightly thicker and warmer, which makes them perfect for cooler days. The extra cushioning also helps prevent blisters during long hikes.
If you’re preparing for a multi-day trek, I’d recommend bringing one of each — Icebreaker for warm, dry conditions, and Smartwool for when the temperature drops.
