Care information
International shoe sizes can vary slightly between brands and models. Use your measured foot length as the best starting point, then compare it with the individual brand's size recommendation. Where a product page gives model-specific sizing advice, that guidance should always take priority over a general conversion chart.

International Kids' Shoe Size Conversion
Children's shoe sizing changes from child to youth sizing as feet grow. Measure the child's foot rather than converting from an existing school or trainer size wherever possible.

Never choose a dance shoe from conversion alone. Ballet, jazz, ballroom and character shoes can fit very differently depending on the last, upper material, width and intended level of compression. Use this table to understand international equivalents, then follow the fit advice for the individual shoe.
How to Measure Your Feet for Dance Shoes
Measure both feet while standing, preferably later in the day. Use the longer foot when comparing your measurement with a shoe size chart.
Foot Length
Key MeasurementStand with your heel lightly against a wall and place your foot flat on a sheet of paper. Mark the end of your longest toe and measure the distance from the wall to the mark.
Measure in centimetres for the most accurate comparison with international shoe charts.
Measure Both Feet
Repeat the measurement on the other foot. It is very common for one foot to be slightly longer than the other, so always use the larger measurement when choosing your starting size.
Foot Width
Measure across or around the widest part of the forefoot. Width can be just as important as length in dance shoes, particularly in fitted ballet, jazz and ballroom styles.
Measure While Standing
Take measurements with your full weight on your feet. Standing allows the foot to spread naturally and gives a more realistic measurement than measuring while sitting.
Check the Dance Fit
A correctly fitted dance shoe should feel secure without restricting the toes or causing pressure. Different dance disciplines require different amounts of growing room, compression and heel security, so always follow the model-specific Dance World Fit Advice.
This chart is designed as an international reference rather than a replacement for individual brand sizing. Bloch, Capezio, So Danca, IDS, PortDance, Diamant and other dance footwear brands may use their own conversion systems or fit differently from standard street shoes. Always use the individual product's Dance World Fit Advice where available.

Description
Description
The PortDance Groovies Trainer is what happens when the comfort of a trainer finally learns how to dance. Lightweight, flexible and softly cushioned, this black knitted sneaker is designed for dancers who want freedom through the foot without giving up the familiar comfort of a lace-up trainer.
PortDance Groovies Trainer Personality
Light • Cushioned • Spin-Happy • Easy-Going
Groovies feels reassuringly familiar the moment you put it on, and then you start turning. The sleek Black Knit keeps the look clean and understated, while the flexible construction gives it a much softer, more dance-friendly personality than an everyday trainer. It's the sort of shoe you put on for one class and accidentally leave on for the rest of the evening.
PortDance Groovies Trainer - Design & Performance
The biggest difference between Groovies and an ordinary sneaker is underneath. Its split-sole construction allows the forefoot and heel to work more independently, giving the shoe far greater freedom through the arch and making detailed footwork feel considerably less restricted.
The lightweight PU outsole includes dedicated spinning points, designed to reduce unnecessary drag through pivots and turns. That makes Groovies particularly appealing for Salsa, Bachata, Kizomba, social Ballroom and other dance styles where repeated rotation can make a regular rubber trainer feel far too sticky. PortDance specifically designed the Groovies sole around smooth, fast turning and fluid movement.
Above the sole, the breathable knitted textile upper is soft and flexible around the foot, while a removable anatomical insole adds cushioning and support beneath it. The result is a shoe that feels much closer to a comfortable everyday trainer while still responding like footwear made specifically for dancing.
And unlike a traditional heeled practice shoe, there's virtually no adjustment period to the height. The low-profile base keeps you close to the floor - particularly useful for dancers who prefer to practise without spending every session in Latin or Ballroom heels.
PortDance Groovies Trainer Technical Profile
The Dance World Technical Profile provides a quick overview of each practice shoe's construction, fit and intended use, making it easier to compare different styles at a glance.

The Dance World Practice Shoe DNA compares the defining characteristics of practice and social dance shoes. A higher score does not necessarily mean a better shoe - it shows the balance of comfort, stability, flexibility, floor control and support so dancers can choose the feel that best suits their dancing.
Dance World Notes
Yes, the spinning points really matter.
Anyone who has tried Salsa or social dancing in ordinary trainers knows the problem - too much rubber grip and suddenly every turn feels like your foot and the floor are negotiating separate contracts. Groovies keeps the familiar sneaker feel, but the dedicated spinning areas allow the foot to rotate much more freely.
A very good “I don't want heels tonight” shoe.
Ballroom and Latin dancers don't always want to practise every hour in their performance heels. Groovies gives you a flat, cushioned alternative while still allowing turns and footwork to happen properly - particularly useful for long workshops, social nights and rehearsal days when comfort eventually wins the argument.
But don't confuse them with running shoes.
They may look like trainers, but the split sole and spinning points are designed specifically around dance movement. That's exactly why they feel so different through turns. We'd keep them for studio, social and dance-floor use rather than treating them as your everyday outdoor walking shoe.
And the removable insole is more useful than it sounds.
You can take it out to air the shoe after a long session, or replace it if you use your own preferred insert.
