PEAK UP30 4.0 | Men’s Carbon Plate Marathon Training & Racing Shoes

Introducing the PEAK UP30 4.0 – the “Energy Giant” of 2025 marathon training shoes, built to boost speed and endurance for every runner. Engineered with a dual-layer high-performance TAICHI midsole (76.8% energy return) and Tianji Carbon Claw, it balances lightweight agility (222g/US7) with long-lasting cushioning, making it your go-to for all training and race scenarios.

Whether you’re logging LSD long runs, pushing speed intervals, or competing on race day, this shoe delivers consistent, non-decaying bounce (≤5% cushioning loss after 20,000 impacts) and smooth propulsion. Its breathable, quick-dry upper and all-terrain outsole keep you comfortable and stable across tracks, roads, and more—designed to power your PB breakthroughs.

Core Technology & Key Features

* Dual-Layer High-Performance TAICHI Midsole (76.8% Energy Return)
Upgraded TAICHI foam (9.8% higher return than prior generations) offers responsive, energy-dense bounce. With a permanent deformation rate ≤30% and ≤5% cushioning loss after 20,000 impacts (simulating a full marathon), it maintains stable support for late-race sprints and high-volume training.
* Tianji Carbon Claw: Flexible, Efficient Propulsion
Bionic toe-bone carbon plate with hollow cutouts reduces weight while extending rolling arc and rigidity. It converts impact energy into smooth forward push, ideal for daily training intensity (no aggressive force—just natural, efficient strides).
* Lightweight, Breathable Upper System
    * Woven Mesh Upper: Quick-dry, breathable, and lightweight, meeting marathon shoe demands for ventilation.
    * Breathable Tongue: Woven material enhances airflow while keeping weight low.
    * Lightweight Heel Lock: Curved heel design ensures a secure fit without extra bulk.
* 
* All-Terrain Hollowed Wear-Resistant Outsole
Hollowed rubber outsole balances durability (focused wear zones) and weight reduction, gripping tracks, roads, and wet surfaces reliably for all-scene adaptability.
