Gumbies Duckbill Flip-Flops Review — Waterproof, Sustainable, and Ready for Adventure
If you want a pair of men’s flip-flops that can handle sand, docks, river rocks and a quick run to the café, the Gumbies Duckbill (Men’s — Black & Grey) deserves a close look. Priced at $35 and built with recycled materials and a rugged sole, these amphibious flip-flops aim to bridge casual comfort and functional water performance. In this review I break down what they do best, where they fall short, and who should consider buying them.
Quick overview: What the Duckbill flip-flops are
The Duckbill from Gumbies is a 100% waterproof flip-flop designed for use on land and water. Key highlights:
- Price: $35 (USD)
- Sizes: US7 — US15 (men)
- Materials: Gumtread™ recycled rubber outsole, textured EVA footbed, recycled PET woven strap
- Use case: Beach, pool, docks, boat decks, light trail access, everyday summer wear
Why these flip-flops stand out
The Duckbill is built for wet environments without sacrificing everyday comfort. If you regularly switch between water and pavement, these flip-flops are engineered to reduce slips, dry quickly, and last longer than typical cheap sandals.
Core features and real-world benefits
- Gumtread™ recycled rubber outsole
Why it matters: Provides tyre-like grip on slippery surfaces. Benefit: Less slipping on wet boat decks, docks and river rocks—confidence when pace or footing change quickly.
- Textured EVA top layer (amphibious upper)
Why it matters: Channels air and water underfoot to keep traction even when wet. Benefit: Secure footing while swimming, cliff-jumping, or stepping out of a kayak.
- Recycled PET woven strap
Why it matters: Lightweight, waterproof and gentle on skin. Benefit: Eliminates soggy straps that chafe; holds the foot securely for active beach days.
- Sustainability — Plant a tree
Why it matters: Each purchase plants a mangrove tree in Africa through Gumbies’ VERDN partnership. Benefit: Small, meaningful environmental impact with community benefits.

Fit, comfort, and performance
The Duckbill runs true to size for most wearers. The strap is woven for support rather than being a flimsy thong—this helps stabilize the foot during short walks or while moving on uneven surfaces.
- Comfort: The EVA footbed offers a springy, cushioned feel; not as plush as thick foam sandals, but comfortable for hours of wear.
- Grip: Outstanding on wet surfaces thanks to Gumtread™ outsole and textured upper.
- Durability: Built to last longer than single-season flip-flops—Gumtread rubber holds up well on abrasive surfaces.
Care tips
- Rinse with fresh water after saltwater use and let air-dry.
- Avoid long-term sun exposure when not in use to prevent faster material breakdown.
- Brush off sand from grooves to maintain traction.

“If you’re looking for a no-fuss, waterproof flip-flop that won’t betray you on wet surfaces, the Gumbies Duckbill delivers performance at a fair price.” — Product test summary
Who should buy the Gumbies Duckbill — and who shouldn’t
Buy if:
- You need a versatile, waterproof flip-flop for beach, boat or pool use.
- You prefer eco-conscious brands using recycled materials and supporting reforestation.
- You want a durable, grippy sole that handles wet and mixed surfaces.
- You’re on a budget but want better performance than basic disposable flip-flops.
Don’t buy if:
- You need maximum arch support or very plush cushioning for long-distance walking.
- You prefer leather or fashion-forward sandals for formal casual wear.
Final verdict
The Gumbies Duckbill flip-flops are a smart purchase for anyone who spends time around water and wants a reliable, affordable, and eco-aware sandal. At $35, they offer excellent wet traction, durable recycled materials, and a supportive strap that stays comfortable once broken in. They’re not a replacement for performance hiking sandals or orthotic footwear, but for beachgoers, boaters, and travelers looking for a single pair to cover both land and sea, the Duckbill is a top contender.
Recommendation: Buy if you value waterproof performance, grip and sustainability. Skip if you need heavy-duty foot support for long urban hikes.
