Two nostalgic sandals dominate the summer shoe conversation in 2026: jelly slides and wedge flip flops. While most coverage stops at “it’s trending” plus a shopping link, this ranking digs deeper into which one actually deserves a spot in your closet.
Why jelly slides are the it-shoe of summer 2026
Jelly shoes made a serious fashion comeback in 2024 with The Row’s netted Mara flat, gained momentum in 2025 through Skims and Melissa, and remain strong now. According to WWD, the trend has expanded beyond flats into slides, kitten heels, and flip flops, shifting from pure nostalgia toward more surreal shapes.
The slide is the version doing the heavy lifting in real life. It’s a one-piece molded PVC or TPU upper over an open, backless footbed you simply step into. The newer generation adds a cork or cushioned insole and a single adjustable top strap, so your foot isn’t gripping the shoe to keep it on.
That redesign is key. Modern jelly sandals use cork footbeds, cushioned insoles, and softer PVC instead of the stiff, blister-inducing plastic of the past. This transforms them from a shoe you tolerate to one you reach for. Red is the top trending jelly color this season, with color-blocked and two-tone styles close behind.
Wedge Flip Flops: Slim and Architectural
The ’90s wedge is also a top summer 2026 trend, but reissued smaller and sharper. Instead of the bulky cork platform of peak Y2K, the cut is slim and architectural — micro-wedges and sleek wedge flip flops. Structurally, it keeps the flip-flop toe post but sets it on an angled wedge, lifting your heel while the sole stays one continuous piece.
Styled right, the result is more “understated European summer” than “spring break.” Pair the slim wedge with clean lines — tailored trousers, a linen shirt, or a slip skirt — and it reads editorial rather than dated. It’s an easy way to add polish without committing to a real heel.
The trade-off is built into the design: your foot still clenches the toe post to hold the shoe on, and the thong sits between your toes all day. This can aggravate hammertoes and bunions over long periods, and the raised sole is less stable on uneven ground.
Expect to pay $60 to $200 for wedge flip flops, depending on the brand.
Square-Toe vs. Classic Thong: Comfort Debate
The square-toe vs. classic thong debate comes down to how much your feet have to work. A classic thong sits on a flat footbed with a toe post, while newer square-toe and slide-style flip flops swap that toe post for a single band across the foot. Both are barely-there and breathable, but flatness is the issue.
A dead-flat footbed lets your foot over-flatten with every step, offering no shock absorption on hard pavement. The single-band slide silhouette usually wins on comfort because your toes aren’t clenching to keep the shoe on. That’s why the adjustable-strap jelly slide outperforms the thong on longer days.

The thong still has a place; it’s the lightest, most packable option for the beach or short errands. Just don’t expect it to handle a full day of walking.
According to the American Podiatric Medical Association, flip-flops offer no arch support, no heel cushioning, and no shock absorption. Overuse can lead to arch and heel pain, tendinitis, and even sprained ankles.
Foot Health: Supportive Alternatives
An open, non-supportive sandal makes your foot work harder, increasing the load on the plantar fascia. A supportive alternative does the opposite: a contoured footbed cradles the arch, a deep heel cup keeps the heel from splaying, and a sole that doesn’t fold flat gives your foot something to push against.
Summer heat adds another challenge: swollen, sweaty feet that tighten whatever you’re wearing, ramping up friction and inviting blisters. Open shoes with adjustable straps and breathable materials help, another point for the jelly slide.
Hot pavement is a genuine burn risk: blacktop can reach roughly 140°F on an 85°F day. A wedge lifts your sole slightly off the ground, while a flat thong keeps your foot close to the heat.
Jelly Slides: The All-Around Summer Winner
The best all-arounder for real summer days is the cushioned or cork-footbed jelly slide. They combine the season’s look with waterproof, wide-toe comfort, and are easy to wear from pool to errands.
The tiebreaker is always the footbed. On hot pavement days and long walks, a contoured, cushioned base beats a flat one every time.
How to Choose the Right Flip-Flop for Your Feet
The key to selecting a flip-flop lies in the footbed and silhouette. Flat thong styles, while lightweight and packable, offer no arch support and lack shock absorption, making them unsuitable for extended wear. The American Podiatric Medical Association warns against their overuse due to risks like arch pain and tendinitis. In contrast, contoured or cushioned footbeds, often found in jelly slides, provide better support and comfort for longer periods.
Material and care also matter. PVC can heat up and become slippery when wet, but dusting feet with powder and opting for cork insoles can mitigate these issues. Rinsing and air-drying after pool use maintains grip, while storing jellies away from direct sunlight prevents warping. Ultimately, the best flip-flop balances style with functionality, prioritizing foot health and the demands of your daily activities.
