A true, tailored fit. Piece together your perfectly tailored fit with our Sole Saver Pack®. The genius components found in your newly purchased shoes (two full-length footbeds, two half-length footbeds and two forefoot cushions to be exact) and complementary bag that come in every box of boots, sneakers and most flats for you to mix‑and-match according to your needs. We created this pack because no two feet are the same—narrow, wide, bunioned or not—we want to help FRANKIE4 shoes fit every unique foot like a glove.

WIDE FIT:If you have bunions, a neuroma, hammer toes or simply just wide feet—you’ll love our half-length footbed. These footbeds free up maximum volume in the front of the shoe. They also feature the same super-soft arch support as our full-length footbeds. Choosing our half-length footbed keeps shoes looking sleek and slimline, while cleverly creating space for feet to breathe.
NORMAL FIT:Foot not wide or narrow but somewhere in between? Try our full-length footbed. Designed with layered contouring to support your arch, cradle your heel, and cushion your forefoot. If they feel snug but not too tight, they’re just right.
NARROW FIT:Narrow feet? We’ve got you cosy and covered. Slip a forefoot cushion under the front of the full-length footbed, towards the front of the shoe to secure a more foot-hugging fit.

Not Your Standard Shoe: Built-In Features
Podiatrist-Designed Footbed
Our unique Sole Hero® Support Footbeds are Podiatrist designed and found in all styles, except our LuxaLite range®.
Depending on the style, they are either built-in or adjustable. This style features a built in Sole Hero® Support Footbed designed with the aim to alleviate and prevent heel pain (including Plantar Fasciitis), arch pain, and forefoot pain through 2 key elements:
- Align: The Footbed contours were designed with the aim to help facilitate better alignment and movement through the foot and leg by supporting the heel and arch.
- Cushion: The Sole Hero® Footbed is loaded with cushioning where it is needed. Our contoured layered system is designed to aid in shock absorption and enhance the feeling of softness under foot. To put it simply, our aim is for the shoe (including this footbed) to help take the stress of standing and walking on hard surfaces, and the wearer to feel their feet are walking on clouds.
Patented Construction: Ballet Flats
The classic ballet flat has long been a wardrobe staple: timeless, versatile, and effortlessly elegant—but traditional pairs leave arches unsupported, toes cramped, and comfort compromised.
At FRANKIE4, we don’t just recreate ballet flats; we reinvent them from the inside out with patented construction* that delivers real, all-day support, cushioning, and performance. Not a gimmick, but thoughtful engineering you can actually feel.
Every detail, from hidden heel elevation to podiatrist-designed footbeds, works together in a one-of-a-kind way that’s genuinely unlike anything else on the market. Learn more here.
*Patent applies to specific ballet flat styles: Dorset and Trinity.

Our designs are improving the quality of life for many women around the globe - the reviews speak for themselves.
Goldilocks Heel Counter
We believe comfort should never come at the cost of support, or vice versa. That’s why we developed what we call the Goldilocks Heel Counter: a heel counter that strikes the perfect balance between structure and softness, not too firm, not too soft, just right.
Crafted from a modern, forgiving thermoplastic, our heel counters are designed to be firm enough to play their essential role, helping to hold your foot securely in place and promoting alignment with every step. At the same time, they are gentle and flexible enough to move with your foot, minimising pressure and reducing the risk of rubbing or irritation against the skin.
What makes this feature even more intelligent is its ability to adapt to you over time. The thermoplastic gently responds to your body heat, softening slightly with wear. As you move, the material gradually moulds to your heel’s unique shape, providing a personalised fit that improves with each wear.
The result? A heel counter that offers the structure you need, the comfort you deserve, and the adaptability your feet will thank you for. It’s just one of the many thoughtful details we build into every pair.
Responsible Leather Sourcing
We’re members of the Leather Working Group (LWG), the world’s leading responsible leather organisation. Over 90% of the leathers used in our styles come from LWG Gold Rated tanneries, with the remainder from LWG Silver Rated tanneries.
This reduces the use of toxic or hazardous substances, reduces pollution, and aids with water management.

Gorgeous ballet flat. Exactly what I was looking for. Due to the cold and wet Melbourne weather I haven’t had a chance to wear them yet. Will be taking them overseas at the end of the month and I am sure they will be comfortable from the first wear like all my other Frankie 4 shoes.
