Kailas Fuga EX 3 vs EX 330 vs EX Pro: What’s the Difference?
Kailas offers three high-performance trail running shoes in the Fuga EX series — EX 3, EX 330, and EX Pro. At first glance, they look similar, but each one is built for a slightly different purpose. Here’s a breakdown that makes it clear.
1. Midsole & Cushioning
Fuga EX 3: Uses ECCEVAI foam, stable and durable, with improved rebound over older versions. Great for everyday ultra training.
Fuga EX 330: Switches to supercritical foam that’s thicker (+21%) and bouncier (+23%) than EX 3. Softer and more energetic, ideal for very long runs.
Fuga EX Pro: Combines supercritical foam with a carbon plate for speed, efficiency, and stability on climbs and descents. Race-ready feel.
2. Stack Height & Drop
EX 3: 8 mm drop (stack height not officially listed).
EX 330: Around 34/39 mm stack, 5 mm drop (most retailers list these specs).
EX Pro: 30/35 mm stack, 5 mm drop. Lower drop helps with a natural stride.
3. Weight
EX 3: ~285 g (EU42).
EX 330: ~300–310 g (slightly heavier due to more foam).
EX Pro: ~275 g (the lightest, despite the carbon plate).
4. Outsole & Grip
All three use Vibram® Megagrip for wet/dry traction.
EX 330 & EX Pro feature Litebase + Traction Lug for better grip and reduced weight.
EX Pro has the most advanced outsole design with a five-zone lug system for climbing, braking, and stability.
5. Upper & Fit
EX 3: Engineered mesh with TPU overlays.
EX 330 & EX Pro: Upgraded XDiMESH — lighter, more breathable, and more durable.
All models use the AWS 3.0 lace system, which splits tension zones to lock down securely without toe pain on descents.
6. Price Positioning
Fuga EX 3: ~US$179 – best value, everyday ultra trainer.
Fuga EX 330: ~US$199 – extra cushion for ultra-distance comfort.
Fuga EX Pro: ~US$300 – plated, lightweight, built for racing.
✅ Which One Should You Choose?
Fuga EX 3: Best for daily training and those who want a stable, do-it-all ultra shoe.
Fuga EX 330: Best for runners who want maximum cushioning and rebound for very long runs.
Fuga EX Pro: Best for racing or faster efforts, thanks to the carbon plate and lighter weight.
👉 In short: EX 3 = Reliable trainer, EX 330 = Max-cushion comfort, EX Pro = Lightweight racer.
