The Y-3 Regu takes its cues from an influential early-2000s shoe — the Mei — and reinterprets the provocative design for today. Its slim, low-profile silhouette is crafted with premium materials including a full leather upper, a fold-over leather tongue, a leather lining and leather at the heel and toe. The tooling is enhanced with a slim Torsion plate, which connects the heel and forefoot.
