So these guides start with what you already own and say when an upgrade is worth it. They cover what to wear on your feet, from running shoes to hiking boots, and how to layer your clothes from a first hike up to a cold summit.

A straight answer for anyone standing in the shoe aisle wondering if sneakers are fine or if they need to spend $150 on boots.

What each layer does, what to wear first, and when an upgrade is worth the money.
