I would like fitting advice. What do I need to measure?

If you’re emailing us for fitting advice, please let us know the following by sending it through to

  • Your shoe size according to our measurement guide
  • The width of the bunion of each of your feet, as measured around the bunion
  • A picture of your feet would be helpful too

I'm unsure about what size to order.

If you’re not sure about which size to order, then our shoe size guide on our website should be able to help you click here to view it.

The size guide will tell you your shoe size you need to fit comfortably in our shoes and most people find that our shoes are ‘true to size’ – this means you don’t have to size up your shoes to accommodate your bunions.

Additionally, if you let us know your feet measurements (the width of the widest place on each of your feet, as measured around the bunion) and send us a picture of your feet, we can help you determine whether our shoes will be suitable for your bunions. Please send any queries to

Do the shoes come in different widths?

All Calla shoes are made in one width only.

This is usually between an E and an EEE in the toe box and a standard D fit everwhere else.  

Some styles are more generous than others so if you are unsure about your sizing you should email 

I'm unsure if the shoes will fit my bunions.

If you let us know your feet measurements (the width of the widest place on each of your feet, as measured around the bunion) and send us a picture of your feet, we can help you determine whether our shoes will be suitable for your bunions. Please send any queries to

Which shoes are better for larger bunions?

The AVA kitten heel, STAR trainer, the Chelsea style boots and the ESME block heel are some of our widest offerings and will therefore be able to accommodate larger bunions that the rest of our shoes. 

To be sure of the exact fit, please email us your shoe size and the measurements of your feet (as measured around the bunion on each foot), along with a picture of your feet to

Shoes only come in one width which is around EE-EEE fitting in the toe box, and standard width in the back of the shoe.

Will the shoes fit me if I only have a bunion on one foot?

It is actually quite beneficial for your non-bunioned foot to be in a wider toe-box.

All of our shoes (except for the ESME block heel and other wide fit styles, which are wide-fit shoes all around) are a standard fit across the back of the shoe and an EE-EEE fit in the toe box. The wider toe-box provides your toes with 'breathing' space and allows them to not be squished, as it normally happens in standard-fitting shoes. The standard fit across the back of the shoe ensures that your foot is securely in place.

Customers outside the UK will have to pay for the postage of their shoes when they are returning them.  

How long does it take for my order to be refunded?

We are happy to refund unworn items within a 30-day period (from the day the goods were delivered to you).

You'll receive an email to confirm when we have received the item at the warehouse, after which your refund will appear in your account within 5 days. This shouldn't take longer than 14 days from the day that you returned the item back to us.

The Shoes

I need to break in my new shoes. How do I do this?

If your shoes are rubbing at the heel we suggest using vaseline rubbed on your foot and on the shoe to reduce the friction between your foot and the shoe which causes rubbing.  Of course you may not want to use vaseline on your new shoes so we would also advise buying a 'moleskin' felt pad for the back of the shoe and rubbing vaseline on that instead. 

Here is a link to one we’ve found on Amazon but all larger chemists should sell a similar product.

You can also see our care guide for advice on stretching your shoes.

What are the soles on your shoes like?

The soles are flexible on most of the shoes. 

What are the insoles in your shoes like?

The insoles on all of our shoes are non-removable and cushioned, except for the 'Star' trainers which have fully removable insoles.

Do your shoes have arch support?

Most of our shoes feature a cushioned and mild arch support insole.

Which styles are wide fitting?

Many of our shoes can accommodate up to an EEE width fitting but only across the widest part of the foot - the rest of the shoe, e.g. the heel, is a standard fit.

Esme and Star are our style recommendations for wide feet and larger bunions.

Are your shoes suitable for post op feet?

Many customers find our shoes suitable for post-operative footwear, especially if the operation in question was a bunionectomy, as they don't have any seams and come up higher on the foot and so cover scarring.
