For dusty mountain tracks with narrow twist and turns, the women’s SWITCHBACK ISO Trail Running Shoes deliver a foot-hugging fit aided by BOA Technology. The BOA System allows you to dial in the lacing and combines with Saucony’s ISOFIT construction for a quick-fitting and ultra-precise feel. A low-profile EVERUN contoured midsole gives amazing flex and energy return while still protecting your foot. Dual-density PWRTRAC outsoles have a firmer center footprint and softer, tackier perimeters, giving you all-purpose traction for tricky obstacles.
