While you technically can wear normal sneakers or running shoes for light trekking on well-maintained, flat trails, it is generally discouraged for anything more ambitious. Normal shoes lack the deep lugs required for traction on loose dirt, mud, or wet rocks, which significantly increases your risk of slipping. Furthermore, trekking-specific boots or shoes are designed with stiffer soles to protect your feet from the constant pressure of jagged stones and provide essential ankle support to prevent sprains on uneven terrain. Normal footwear often has a thinner "upper" that can easily tear or allow water to soak through, leading to damp feet and painful blisters. In 2026, most outdoor experts recommend at least a "trail runner" if you prefer lightness, but for multi-day treks or steep inclines, the durability and protection of a dedicated trekking boot are indispensable for safety and comfort.
