Revitalign Fusion Energy Flip Flop | Orthotic Comfort Sandal
The Revitalign Fusion Energy flip flop brings podiatrist-designed orthotic technology to your everyday sandal. We engineered this style around our patented contoured footbed system that realigns your stride from the ground up, reducing stress on ankles, knees, hips, and lower back with every step.
Whether you’re running errands, walking the boardwalk, or unwinding poolside, the Fusion Energy delivers the structured arch support your body needs without sacrificing the easy slip-on convenience you want. Our moisture-wicking Silpure-treated footbed keeps feet fresh and dry all day, while the shock-absorbing midsole cushions impact on hard surfaces. This isn’t a traditional flip flop that leaves you fatigued by midday—it’s a biomechanically optimized sandal that helps you move better and feel stronger hour after hour.
Built-in orthotic technology & design details
Biomechanical footbed alignment system
Our patented orthotic footbed sits at the heart of the Fusion Energy flip flop. We designed it in collaboration with podiatrists to mirror the natural contours of a healthy foot, with a deep heel cup that centers your heel bone, a sculpted arch that supports your longitudinal arch, and a metatarsal pad that redistributes pressure across the ball of your foot.
This three-point alignment system corrects overpronation—the inward rolling motion that happens when your arches collapse during walking. By stabilizing your foot in a neutral position, the footbed reduces excessive rotation at the ankle and knee, which can lead to plantar fasciitis, shin splints, and joint pain over time. Many customers tell us they notice less end-of-day fatigue in their legs and lower back once they switch to Revitalign footwear for their daily activities.
Sizing, fit, and break-in guidance
Order your usual women’s shoe size for the Fusion Energy flip flop. The footbed runs true to size with a medium width profile that accommodates most foot shapes. If you typically wear a men’s size, subtract 1.5 sizes to find your women’s equivalent—for example, a men’s 8 corresponds to a women’s 9.5.
Because the orthotic footbed provides structured support, you may feel firmness underfoot during the first few wears. We recommend breaking in your sandals gradually: wear them for an hour or two on day one, then increase by an hour each day until your feet adapt to the corrective positioning. Most customers report full comfort within three to five days. The nylon toe post features a soft padded collar that prevents irritation between your toes, even during the break-in period.
Materials, care, and durability
Construction details
The Fusion Energy flip flop combines premium materials engineered for longevity. The compression-molded EVA midsole delivers responsive cushioning that won’t compress flat over time, while the rubber outsole features strategically placed flex grooves that encourage natural foot motion without sacrificing traction. Our Silpure antimicrobial treatment penetrates the entire footbed layer, providing continuous odor protection that won’t wash away.
Cleaning and maintenance
Wipe down your sandals with a damp cloth and mild soap after beach or pool days. Air-dry them away from direct heat or sunlight to preserve the EVA’s shock-absorbing properties. Do not machine wash or submerge in water for extended periods. With normal wear, the footbed and outsole should maintain their supportive structure for 500-plus miles of walking. Replace your sandals when you notice visible compression in the arch area or worn-through tread on the outsole.

Common questions about the Fusion Energy flip flop
The Fusion Energy features a podiatrist-designed footbed that provides many of the same biomechanical benefits as custom orthotics, including arch support, heel stabilization, and pressure redistribution across the metatarsal heads. While custom orthotics are molded to your specific foot shape, our contoured footbed is engineered to support the average foot anatomy in a neutral aligned position.
Many customers with custom orthotics use the Fusion Energy as their warm-weather alternative when they need open-toe footwear. If you have severe structural abnormalities or complex foot conditions, we recommend consulting your podiatrist to confirm that an over-the-counter orthotic sandal meets your therapeutic needs.
The Fusion Energy flip flop has a medium width profile that accommodates most foot shapes, including moderately wide feet. The open design and adjustable toe post provide more lateral room than closed-toe shoes. However, if you typically require a wide or extra-wide width in traditional footwear, the structured footbed may feel snug across the midfoot.
We suggest ordering your usual size and taking advantage of our 30-day comfort guarantee. Many wide-footed customers report that the footbed conforms slightly during the break-in period, creating a custom-like fit. If the sandals feel uncomfortably tight after breaking them in, you can exchange for a half size up or return for a full refund.
With normal daily wear, the compression-molded EVA footbed retains its structural integrity for approximately 500 miles of walking, which typically translates to 6-12 months depending on usage frequency. The footbed is designed to resist compression breakdown better than traditional foam flip flops.
You’ll know it’s time to replace your sandals when you notice visible flattening in the arch area, reduced cushioning underfoot, or worn-through sections on the rubber outsole. To maximize longevity, avoid leaving your sandals in direct sunlight or hot car interiors, as excessive heat can accelerate EVA degradation over time.
Yes, the Fusion Energy flip flop performs well in beach and poolside environments. The materials are water-resistant, and the Silpure-treated footbed inhibits bacterial growth even when exposed to moisture. The rubber outsole provides reliable traction on wet surfaces.
After water exposure, we recommend rinsing off sand and salt, then air-drying the sandals away from direct heat. While the Fusion Energy handles occasional water contact beautifully, it’s not designed for continuous submersion. If you need a sandal specifically for in-water activities like kayaking or river walking, consider our Splash Waterproof model, which features sealed construction throughout.
Many customers report significant plantar fasciitis relief after switching to the Fusion Energy flip flop, thanks to the deep heel cup and contoured arch support that reduce strain on the plantar fascia ligament. The orthotic footbed helps maintain your foot in a neutral position that minimizes overstretching of the fascia during walking.
That said, plantar fasciitis has multiple contributing factors, and footwear is just one component of effective treatment. We recommend using the Fusion Energy as part of a comprehensive approach that may include stretching exercises, rest, and guidance from a healthcare provider. Our 30-day guarantee lets you test whether the sandals provide meaningful symptom relief for your specific situation.
The Fusion Energy is built on a women’s size scale, but the biomechanical design and unisex colorways work well for men who fall within the available size range. To find your equivalent size, subtract 1.5 from your men’s shoe size—for example, a men’s size 9 would order a women’s size 10.5.
The orthotic footbed technology is identical across our entire sandal line regardless of gender sizing. Men with larger feet beyond the women’s size 12 range should explore our men’s-specific orthotic sandal styles, which offer the same biomechanical benefits in extended sizing.
No, the Fusion Energy flip flop is designed for barefoot wear. The Silpure antimicrobial treatment embedded in the footbed continuously inhibits odor-causing bacteria and fungi, keeping your sandals fresh even with daily barefoot use. The moisture-wicking top layer also helps prevent the damp environment where bacteria thrive.
For maximum hygiene, simply wipe down the footbed with a damp cloth and mild soap every few weeks, or more frequently if you wear the sandals in sweaty conditions. The treatment remains effective throughout the life of the sandal and won’t wash away with routine cleaning.
