Qiaodan TG 2.0 LEILI 2.0 "Oxygen Cleansing" QDB023264285 - Unisex Running Shoe Blue
Breathe In. Bounce Forward.
The Qiaodan TG 2.0 LEILI 2.0 "Oxygen Cleansing" (QDB023264285) — globally marketed as the LEILI 2.0 'O2' — is an elite unplated daily super-trainer meticulously engineered for long-distance training miles, easy recovery runs, and everyday road work. It delivers a highly responsive, plush underfoot feel at an exceptionally lightweight build — the kind of shoe that makes easy days genuinely feel easy.
Design Concept
The "Oxygen Cleansing / O2" colorway leans into a fresh, airy, health-inspired technical aesthetic. Light, clean-tinted neutral tones are paired with oxygen-blue and minty-green gradients pulsing across the midsole — mirroring a sense of refreshing respiration and continuous energy flow. The result is a sleek, breathable silhouette that visually dissolves its massive 44mm stack height into something that feels as light as it looks.
44mm Full-PEBA Midsole Matrix
A massive 44mm heel stack height built entirely from a premium 100% full-PEBA compound compresses beautifully under weight to absorb harsh tarmac impact, then fires back with an aggressive 84% energy return. Plate-free by design — pure foam, pure responsiveness.
Centered Fluid Rocker Geometry
An upgraded, early-stage rolling rocker curvature with a stable 7mm heel-to-toe drop guides the foot forward naturally using foam geometry alone — no carbon, no nylon shank. The result: smooth, effortless transitions that eliminate muscle fatigue in the foot arch across long easy mileage.
Ultra-Breathable Mono-Mesh Upper
A featherlight, highly porous engineered knit frame drops total shoe weight to a nimble ~221g (US Men’s 8). Rapid heat dissipation and optimal airflow keep feet cool and comfortable through warm-weather training sessions — structure without suffocation.
Q-ASU Anti-Slip Outsole
Segmented tread using Qiaodan's elite Q-ASU marathon-grade CPU rubber delivers secure, quiet traction across wet and dry urban roads without hindering the natural flexibility of the soft PEBA foam base — grip that stays out of the way.
Sizing Advice
- True to size (TTS) in length with an accommodating medium fit and increased width through the midfoot and forefoot compared to narrow racing lines — the single-layer mesh shapes comfortably around standard feet.
- Go half a size up if you have exceptionally wide feet or a high instep — micro hot-melt structural lines at the front toe boundary ensure containment over the plush stack height, which can limit room during extended late-stage foot swelling.
