# Onitsuka Tiger Premium Nappa Leather Sneakers in Slate Grey/Navy
## Brand Aesthetic Philosophy
Onitsuka Tiger's design ethos marries Japanese minimalism with athletic heritage, evident in these sneakers that reinterpret 1970s sports aesthetics through contemporary lens. The brand's signature serrated tiger stripe motif is subtly integrated into the silhouette, paying homage to its Tokyo Olympics origins while maintaining urban sophistication. Each stitch follows the traditional 3:2:1 construction ratio favoured by Japanese shoemakers, creating visual rhythm without overt branding.
## Product Narrative
Crafted from full-grain Nappa leather sourced from Italian tanneries, the upper develops a distinctive patina over time. The leather undergoes 12-hour drum-dyeing process to achieve the nuanced slate grey/navy gradient. Reinforced eyelets feature brass grommets with micro-brushed finish, while the padded collar uses memory foam typically reserved for performance footwear. The outsole combines compression-molded EVA with gum rubber inserts for 47° shore hardness - the optimal balance between flexibility and rebound. Inside, vegetable-tanned leather lining wicks moisture through capillary-action perforations.
