Z/1 Classic
Built like a tank with a focus on foot alignment. The Z/1 is famous for its 'ReChaco' program, where the brand will replace the straps and the sole, essentially giving the user a new sandal for a fraction of the price.
Ingredients & Purity
Uses a dual-density PU (polyurethane) midsole. While synthetic, PU is far more durable and compression-resistant than the EVA used in most sandals.
Scientific Evidence
Features the LUVSEAT footbed, which is podiatrist-certified (APMA) for all-day comfort and support.
Brand Transparency
Chaco is highly transparent about their repair process (ReChaco), providing clear pricing and turnaround times for resoling and strap replacement.
Value Assessment
Excellent value due to the sheer lifespan of the PU footbed, which can easily last 15 years with 2-3 resoles.
Why Not Alternatives?
Beats competitors like Teva because the straps are one continuous piece that wraps through the midsole, allowing for a custom fit that never stretches out or detaches.
