Dior B30 Sneaker — Slate Blue Grey Tonal, CD Logo Relief Panel, Men’s EU 38–44

Dior B30 Sneaker — Style 430046

The Dior B30 low-top sneaker in a slate blue grey tonal colorway, men’s sizing EU 38–44. This is the most chromatic of the three B30 colorways presented — where the warm taupe version (Style 430048) reads as a neutral warm tone and the triple black version (Style 430047) reads as an achromatic dark, this slate blue grey occupies a cooler, more distinctly colored register that is still fully tonal in its execution. The color is a muted, desaturated blue-grey — closer to slate or stone blue than to navy or sky, with a cool undertone that reads as urban and modern without approaching any strong chromatic statement. Every element of the upper, lacing system, and sole unit is in this same slate blue grey family, making it the most cohesive single-color expression of the B30 silhouette. The CD monogram relief panels — the defining structural feature of the B30 — are particularly effective in this colorway: the moderate lightness of the slate blue grey tone allows light and shadow to play across the raised letter forms with greater legibility than in the triple black version, while the cool tonal unity gives the relief a more architectural and sculptural presence than the warmer taupe version. The fine embossed surface texture of the overlay panels is more visible in this color than in the darker colorway, contributing an additional layer of material interest to what is otherwise a fully tonal composition. EU 38–44 men’s sizing.

Construction Details

• Silhouette: Low-top lace-up runner with the B30’s characteristic rounded, cushioned profile; in this slate blue grey colorway the silhouette reads with a balanced visual weight — more present than the taupe version, more approachable than the triple black version; the rounded toe box and organic contour suit the cool blue-grey tone, which gives the shoe a refined urban character without the formality of the full-black execution
• Slate blue grey textured nylon and leather overlay panels: The primary overlay panels covering the toe cap, lateral and medial wings, and the heel counter are in slate blue grey matte nylon or leather with a fine embossed or woven surface texture; the texture is more visible in this cooler, mid-tone color than in the darker black version, adding a tactile layer of material detail to the tonal composition; the overlays define the panel structure of the upper alongside the CD relief and the mesh base
• Slate blue grey technical mesh panels: Fine-weave technical mesh in matching slate blue grey covers the central vamp and quarter panels; the mesh is slightly open in texture and reads as a subtly different material zone from the smoother overlay panels, providing material relief within the tonal palette; the mesh tone is consistent with the overlay color, maintaining the full-tonal composition across the upper
• Slate blue grey CD monogram relief panels: The B30’s oversized CD letter forms rendered as three-dimensional sculptural overlays on the lateral and medial sides are in the same slate blue grey as the surrounding materials; in this mid-tone colorway, the relief panels achieve the best balance of legibility and tonal integration across the three B30 colorways — the cool grey-blue tone provides enough reflected light to make the letter forms clearly readable in a range of lighting conditions, while the tonal color keeps the branding within the overall quiet, unified aesthetic of the shoe; the CD relief panels are outlined by their own raised edges and the seam stitching, which in this colorway is also in matching blue-grey (unlike the white contrast stitching of the triple black version)
• Tonal stitching throughout: Unlike the triple black version with its white contrast stitching, all seam and panel stitching on this slate blue grey version is in matching blue-grey tone; the tonal stitching keeps the panel structure understated and the overall surface calm, relying entirely on material texture and three-dimensional relief for visual interest
• Blue-grey Dior tongue badge: A triangular Dior logo badge at the upper edge of the tongue is in matching blue-grey — unlike the silver metal badge on the black version, this badge is color-matched to the upper, making it a tonal brand detail rather than a contrasting accent
• Oval “DIOR” heel badge: A small oval Dior wordmark is debossed or applied to the lateral heel counter in matching blue-grey
• Slate blue grey flat laces and tonal eyelets: Flat laces in slate blue grey thread through color-matched eyelets; unlike the silver eyelets of the black version, the eyelets here are tonal, completing a fully unified upper with no metallic accent
• Slate blue grey layered EVA and rubber sole: The B30’s stacked runner sole is in a slate blue grey that matches the upper precisely — making this the most visually unified sole-to-upper execution of the three B30 colorways; the rubber outsole carries the standard runner tread and debossed “DIOR” lettering on the heel sidewall rubber, both in matching blue-grey; the absence of any contrast color at the sole level makes the shoe read as a single continuous form from lace to ground
• Sizing: EU 38–44; men’s sizing
• Packaging: Dior signature blue shoebox
