Your actual usage pattern matters way more than the brand name on the box. I've seen budget shoes outlast expensive ones when someone takes care of them, and I've watched pricey gear get destroyed by someone who doesn't. That said, Salomon does tend to have better overall construction and materials - they're not just charging for reputation. The stitching holds up, the midsoles take longer to compress, and the outsoles grip longer before they get slick.
Where I'd push back on the previous answer is that this isn't just about leather quality. Salomon also designs their shoes with hiking specifically in mind, which means better arch support systems, ankle reinforcement, and outsole patterns that actually work on varied terrain. Merrell and Columbia make solid shoes, but they're often playing catch-up on these details. If you're doing serious hiking regularly, those design differences add up over time.
The honest take: if you hike a few times a year on mellow trails, a Merrell or Columbia shoe will probably do fine and save you money. If you're out there regularly, pushing into rough terrain, or planning to use the same pair for years, Salomon's engineering tends to justify the cost. Check reviews specific to the model you're eyeing though - not all Salomons are equally durable, and same goes for the budget brands. Fit matters too; a shoe that rubs wrong will wear out or hurt before durability even becomes relevant.
