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.

Podiatrist-Designed Footbed
Over two years in the making, LuxaLite® is a patent-pending footbed design at the intersection of science and style, re-imagining a fashion silhouette and a better foundation than what traditional fashion heels offer.
LuxaLite® is a streamlined, podiatrist-designed footbed which is contoured and moulded with varying densities to deliver slimline, targeted cushioning and support without compromising on style. It has cushioning targeted where higher pressure is most common—this enables footbed compression where your foot craves it in a fashion heel.

Customer Reviews
- JCJayde C.Verified BuyerI recommend this productAge 35-44Size Purchased 8Rated 5 out of 5 stars3 minutes agoSuper comfy and super cute
I absolutely love these shoes! They're such a versatile option that can easily be dressed up for weddings, cocktail events, dinners or any occasion where you want to look polished without sacrificing comfort.
I have ongoing foot problems and my feet get sore very easily. The days of wearing 4-inch heels on a night out are well and truly behind me, so I've been looking for a stylish alternative. These are exactly that. They're comfortable enough to wear for hours, while still looking elegant and feminine.
If you're after a low heel that doesn't compromise on style or comfort, I'd definitely recommend these.
