These are two different kinds of shoe.
The Inov-8 TrailFly Ultra G 280 is a trail running shoe; the Scarpa Zodiac Plus GTX is a trekking boot. The lighter one saves 450 g a pair, but they are built for different kinds of hiking, so the lightest is not automatically the better buy.
What the extra 450 g of the Scarpa Zodiac Plus GTX buys you
- A waterproof membrane (GORE-TEX Performance Comfort), so wet grass, puddles and rain stay outside.
- A higher cut that covers the ankle.
What the Inov-8 TrailFly Ultra G 280 offers besides the lower weight
- No membrane, so it breathes better in the heat and dries faster after a stream crossing.
Weights are per pair as Alpinetrek lists them, usually for a medium size, so a few grams either way can come from the size they weighed. The other specs were checked on 19 October 2026 against Alpinetrek (Inov-8 TrailFly Ultra G 280) and Alpinetrek (Scarpa Zodiac Plus GTX). "Not stated" means the source does not mention it, not that the shoe lacks it. List prices are the full price shown by that source, not a sale price; where sources disagree we show none.
Choose the Inov-8 TrailFly Ultra G 280 if…
…you move fast on trails, run some of it, and want the lightest and most flexible shoe; it gives little ankle support under a heavy pack.
Choose the Scarpa Zodiac Plus GTX if…
…you carry heavy loads on rocky, steep or off-trail ground for days at a time.
