San Ysidro Slide - Raven

All black. No compromise. Deep, saturated black wrapped in plush shearling — Raven is San Ysidro at its most refined. Sleek. Grounded. Effortlessly cool. The kind of slide that works with everything and elevates anything. This is that Fleks feeling — sculpted support hidden inside a silhouette that looks this good. Plush comfort, perfected. Soft shearling across the top. Sculpted support beneath your feet. The San Ysidro Slide is the sandal that captures that unmistakable Fleks feeling. Every Fleks style is built using proprietary Blumaka recycled foam, delivering the perfect balance of plush cushioning and supportive comfort — all while giving new life to materials that would otherwise go to waste. The result is a slide that feels incredibly soft yet surprisingly supportive. Easy to slip on, endlessly wearable, and designed to move with you through the day. This is comfort that doesn’t shout. It simply works. THE FLEKS COMFORT SYSTEM Just-right comfort. Most casual footwear gets one thing right — softness. But softness alone doesn’t support your foot. At Fleks, we designed a system that delivers the balance your feet actually need: plush cushioning, natural support, and stable comfort that lasts all day. Powered by Blumaka Recycled Foam Every Fleks style is built using proprietary Blumaka recycled foam, giving new life to reclaimed performance foam from the athletic footwear industry. Instead of becoming waste, these materials are transformed into durable cushioning that feels great and holds up over time. The Comfort Trifecta At the core is our Signature Sculpted Midsole, designed around the three things your foot actually needs: • Deep heel cup — helps keep your foot secure • Sculpted arch support — encourages natural alignment • Subtle toe bar — helps prevent forward slide The result is footwear that feels soft when you step in, supportive when you move, and comfortable enough to wear all day. Better materials. Less waste. Our foam construction allows us to use up to 85% recycled material by volume, transforming performance foam scrap into long-lasting comfort. It’s a smarter way to make shoes — and a better way to feel good in them. Fit note: This style runs long. If you’re between sizes, we recommend sizing down.
