As the third-generation redesign of the ever-popular Helios, the Helios III offers everything you need in an ultralight and perfectly cushioned trail shoe. We added additional tongue and ankle padding for more comfort on longer runs. A combination of rip-stop nylon and mono-burr inserts enables optimal breathability but also abrasion resistance. The low profile, thermo-formed toe cap provides protection, while the FriXion AT 2.0 rubber outsole is long-lasting and remarkably versatile.
