The Hoka Speedgoat 6 GTX features the legendary Vibram Megagrip outsole with 5mm traction lugs for confident grip across anything from rocks and gravel to grass and woodland paths. An updated midsole compound gives an even more energetic feel across the trails, and is even lighter than previous versions, so you get a faster, responsive feel. An internal support chassis, dynamic vamp, and plusher, dual-gusset tongue all help to give a comfortable locked-in feel, enhanced by the GORE-TEX invisible fit membrane for a waterproof finish.
