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.

Product details
Trinity reimagines the classic ballet flat with a blend of elegance and innovation in refined Black Tumbled. Featuring an almond toe and a delicate bow, Trinity combines luxe handcrafted leather with a sophisticated design. The plush inner also features rPET forefoot lining made from recycled plastic bottles. Adjustable fitting with EVA forefoot cushions ensures a custom feel, while the podiatrist-designed footbed with hidden arch support provides exceptional comfort and support. Trinity is where timeless style meets modern functionality.
If you commonly wear the same shoe size in your FRANKIE4s, we recommend sticking with this. However, if your feet vary between sizes, we suggest starting with the bigger of the two sizes first. We’ve found it’s not uncommon to go up half a size in ballet flats, due to their neat, sleek profiles.

Not Your Standard Shoe: Built-In Features
Podiatrist-Designed Footbed
Our unique Sole Hero® Footbeds are Podiatrist-designed and found in all styles, except our LuxaLite® range. Depending on the style, they are either built-in or adjustable through our Sole Saver Pack® (complimentary). This style features adjustable footbeds to perfect the fit if needed.
The Sole Hero® Footbed featured in this style is designed with the aim to alleviate and prevent heel pain (including Plantar Fasciitis), arch pain, and forefoot pain through 3 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.
- Distribute: The support and cushion system in this footbed features layers of materials with differing softness. Intended to assist with foot cushioning and help spread the load and pressure under the foot- with the aim to reduce pain related to pressure areas.
- Cushion: The Sole Hero® Footbed is loaded with cushioning where it is needed. This is to aid in shock absorption to help take the stress off your foot and leg. To put simply, our aim is for the shoe (including this footbed) to take the stress, whilst helping reduce that stress on your foot and legs.
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.
*Patent applies to specific ballet flat styles: Dorset, Trinity, and London.

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, minimizing 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 personalized 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.

- SISarah I.Verified BuyerI recommend this productAge 45-54Area Of Profession Business, Finance, LawSize Purchased 6.5Rated 4 out of 5 stars4 minutes agoReally wonderful !
Bought these online as the shop in Paddington didnt have my size 6.5. Really great support in a beautiful, classic ballet style flat. Left shoe scraping off the skin a bit as I break them in but will put some adhesive on to solve that problem. Raised inner sole makes me a little taller. Very comfortable otherwise.

I bought these in a panic the day before a 4 week
trip to Europe as the shoes I had planned to take along had fallen apart! I was a bit apprehensive because I hadn’t had time to wear the before the trip and break them in however I was very pleasantly surprised. They were comfortable right from the start and while I didn’t walk for hours and hours in them, I did wear them around town in Zürich and Paris very comfortably whenever I wanted something slightly more chic than my sneakers or hiking Boots, particularly in the evening. Absolutely love these and now want to purchase in more colours as an everyday shoe for both the office and weekends.
