Kitletics Review · 7.5 Solid
Inov8 Trailfly Ultra G 300 Max is a race-trail shoe. Graphene-cushioned max-stack trail ultra shoe for long technical mountain efforts. I'd shortlist it for high trail cushion for ultras. The trade-off is niche retail availability — HOKA Speedgoat 6 is the cleaner compare when that is most of your week. It fits buyers who actually need a race-trail shoe, not a one-product rotation.
