Designed to stand up to the rigour of both road and trail running with a combination of minimal cushioning and a lightweight breathable upper. Dynamic Fascia Band replicates and supports the foot`s plantar fascia ligament and GORE-TEX technology ensures the foot is kept dry. Female specific fit.
Closer to conventional footwear than other boots in the Inov8 collection, the three arrows means greater protection but also the greatest height difference between the heel and foot, this is important because the most natural walking style (i.e. barefoot) does not have any height difference between heel and foot, and as you progress down the inov-8 'arrows' the differential gets smaller, so a three arrow shockzone has 9mm.
Hence, sorry for the waffle, the Terrafly is closer to more conventional footwear in this respect.
