Size Chart - Footwear, Clothing and Accessories
All our footwear is manufactured and sold in UK sizes.
Footwear measurements are displayed in Millimetres (mm). The length is the internal measurement of the footwear from heel to toe.
Clothing & Accessories measurements are displayed in Centimetres (cm)
For your convenience we have prepared this guide to assist you in choosing the correct UK Size when placing your order. We all know that feet come in all shapes and sizes, so the size charts are designed to give you information and guidance to help you make your choice.
Most importantly our Online Team, drawing on the experience with our customers, are here to give you additional expert advice on the most suitable size.
In addition to this size guide, we have also prepared further information according to each Collection. If you choose to measure your feet, then you will need to select a size with a length that is marginally longer than your foot measurement.

| UK Size | 2 | 3 | 4 | 5 | 5.5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 |

Pikes - Flats
The length is the maximum internal measurement for each size. The width is measured at the widest part of the shoe.
Pikes – Important Sizing Information
Pikes have a distinctive, highly elongated pointed toe. Because of this construction, the internal shoe length shown in our size chart is not the same as the recommended foot length.
The measurement shown in the chart is the full internal length of the shoe, including approximately 40 mm of pointed toe space which is not intended to be occupied by the foot.
When choosing your size, we therefore recommend comparing your foot measurement with the recommended foot length, rather than comparing it directly with the full internal shoe length.
For example:
UK3 Pike
Full internal shoe length: approximately 281 mm
Pointed toe allowance: approximately 40 mm
Recommended foot length: approximately 241 mm
If your foot measures around 237–241 mm, a UK3 would therefore be the appropriate size to consider, even though the shoe itself measures approximately 281 mm internally.
How to measure your foot
Measure your foot in millimetres from the back of the heel to the end of your longest toe. We recommend measuring both feet while standing and using the measurement of the longer foot.
Do not add the pointed toe allowance yourself when selecting a size. Use the Recommended Foot Length shown in our Pikes size chart.
Because Pikes are deliberately designed with a long pointed silhouette, there will be significant empty space beyond your toes when the shoe fits correctly. Your toes are not intended to reach the end of the shoe.
| UK Size | 2 | 3 | 4 | 5 | 5.5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Length (mm) | 266 | 274 | 282 | 290 | 298 | 306 | 314 | 322 | 330 | 338 | 346 | 354 |
| Width (mm) | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 |

XX Otranto - Platform Heels
XX Otranto – Platform Heels collection – The length is the maximum internal measurement for each size.The width is measured at the widest part of the shoe.
The XX Otranto has a generous fit, and we recommend selecting one UK size down from your usual size.
When choosing your size, please also pay particular attention to the internal length measurement shown in our size chart rather than relying only on your usual UK, US or EU shoe size.

Our recommendation: size down one UK size from your usual size and check the internal measurement before ordering.
