With its vintage ski boot-inspired D-R Cinch lacing system, the Si-18 International is a timelessly recognizable silhouette.

Customer Reviews (4.8 / 5 · 5 reviews)

Sebastian ★★★★★ Oct 21, 2026

The classic colorway looks even better in person, and the reengineered sole is noticeably more comfortable than the original version I wore years ago.

Alexander ★★★★★ Oct 19, 2026

The bright white with classic blue and red is a clean, retro look that gets compliments every time I wear them. The reengineered cushioning underfoot makes a huge difference for all-day comfort compared to older versions.

Jacob ★★★★★ Oct 18, 2026

The reengineered cushioning is exactly what I needed for all-day wear, and the classic white, blue, and red panels give it that retro 80s look without feeling outdated. They fit true to size and the leather broke in nicely after just a couple of wears.
