Mizuno Wave Ibuki 4 GTX – Waterproof Gore-Tex and Michelin Sole for Technical Trails
The Mizuno Wave Ibuki 4 GTX J1GJ225901 trail running shoe combines a waterproof Gore-Tex membrane, cushioning Wave technology, and a high-traction Michelin sole to offer complete protection, superior stability, and reliable grip on technical trails, wet terrain, and adverse weather conditions.
Waterproof and Breathable Gore-Tex Membrane
The Gore-Tex membrane blocks water, mud, and external moisture, keeping your foot dry during stream crossings, heavy rain, or wet snow. Controlled breathability reduces internal condensation on long 10-30 km trails, preventing blisters from excessive sweating. Gore-Tex certification guarantees total and lasting waterproofing.
Mizuno Wave Technology and Ultra-Soft Cushioning
The Wave plate distributes impacts evenly across the entire sole, protecting joints during steep descents and rocky terrain. The ultra-soft cushioning absorbs repeated shocks, reducing muscle fatigue over medium-long distances. Lateral stability prevents ankle sprains on uneven ground.
Michelin Sole and Extreme Traction
The Michelin rubber sole with aggressive multi-directional lugs guarantees superior grip on mud, wet rock, slippery roots, and mixed terrain. The high-grip compound maintains reliable traction even in extreme conditions (rain, snow, light ice). 40% superior abrasion resistance compared to standard rubbers.
Low Weight 310g and Trail Speed
The weight of only 310g (size 42) balances protection and lightness, allowing for a sustained pace on climbs and fast trails. The optimized construction reduces fatigue on ultra-trails and long races without sacrificing robustness and support.

Who Are They Ideal For
Perfect for intermediate and advanced trail runners who tackle technical trails with mud, wet rocks, stream crossings, and variable weather conditions. Suitable for distances of 10-50 km on non-extreme mountain terrain, entry-level ultra-trails, and four-season training. Ideal for those seeking certified Gore-Tex waterproofing, reliable Michelin grip, and comfortable Wave cushioning. Excellent for autumn-winter-spring trails with frequent rain.
When NOT to Choose Them
If you primarily run on dry summer trails above 25°C, consider models without Gore-Tex for greater breathability (e.g., Wave Ibuki 4 standard). Not suitable for extreme ultra-trails over 100 km (insufficient cushioning for extreme distances - a specific ultra model is needed). The regular fit may be too narrow for very wide feet. Not ideal for fast trail racing under 10 km (310g weight is excessive compared to racing shoes under 250g). Gore-Tex requires periodic maintenance to preserve waterproofing.
Comparison with Alternatives
Compared to Salomon Speedcross 5 GTX, they offer superior Wave cushioning (vs minimal) and 10% reduced weight with similar Michelin grip. Compared to Asics Gel-Trabuco 11 GTX, they have a more reliable Michelin sole (vs ASICSGRIP) and a 20% lower price. Compared to Hoka Speedgoat 5 GTX, they weigh 25% less (310g vs 415g) with superior stability but less cushioning. Compared to the standard Wave Ibuki 4, they have waterproof Gore-Tex vs breathable mesh and a 30% higher price.
Frequently Asked Questions
Are they completely waterproof? Yes, the Gore-Tex membrane guarantees certified total waterproofing. Suitable for short stream crossings, heavy rain, and wet snow. Do not submerge beyond the height of the shoe (water would enter from the collar).
Can I use them in summer? Yes, but only on cool mountain trails or at temperatures below 20°C. Above 25°C, Gore-Tex reduces breathability causing overheating - the standard version without the membrane is better.
How do I choose the size? Regular Mizuno fit: choose your usual trail running size or half a size up if you use thick technical socks or orthopedic insoles. Leave 1 cm of space in front of your toes to avoid compression on descents. Always try them on with trail socks.
