Black and white contrast sharp—geometric minimalism meets advanced cushioning technology.
The Glycerin 21 cuts sharp lines with bold black-to-white contrast and confident geometric branding. The streamlined upper wraps cleanly while the midsole geometry promises smooth, efficient transitions. This shoe balances aesthetics with engineering—it's refined enough for casual style yet serious enough for daily training miles. Wear it when precision matters, whether on pavement or in conversation.
