BLOCH Size & Fit Advice

BLOCH sizing varies between dancewear and footwear styles. For garments, use actual body measurements rather than everyday clothing size wherever possible. For shoes, use measured foot length as your starting point and always follow the model-specific Dance World Fit Advice shown on the individual product page.

Dance World Tip

For BLOCH leotards and other fitted dancewear, girth is particularly useful because it reflects the full length of the torso. For children's garments, use age as a reference only and prioritise actual body measurements whenever possible.

International Kids' Shoe Size Conversion

Measure the child's foot rather than converting directly from an existing school or trainer size wherever possible. Dance shoes require different amounts of growing room depending on the style, so always check the individual BLOCH shoe fitting advice.

Before Choosing Your Size

Take dancewear measurements over underwear or close-fitting clothing using a flexible tape measure. For shoes, measure both feet while standing and use the longer measurement as your general starting point.

Bust / Chest Measure around the fullest part of the chest, keeping the tape straight and level.

Waist Measure around the natural waist, usually the narrowest part of the torso.

Hips Measure around the fullest part of the hips and seat, keeping the tape level.

Girth Start at one shoulder, measure down the front of the torso, through the crotch and back to the same shoulder in one continuous loop.

Foot Length Measure from heel to longest toe while standing. Measure both feet and use the longer measurement as your general starting point.

BLOCH Fit Guidance

BLOCH produces footwear for many different dance disciplines, so there is no single BLOCH shoe conversion that accurately predicts the fit of every model. Ballet, jazz, tap, character, contemporary, dancesport and studio shoes can all use different fitting recommendations. Use the international shoe tables above as a reference only and always follow the model-specific Dance World Fit Advice shown on the individual product page.

Dance World Fit Note BLOCH size charts and Dance World sizing recommendations are intended as a guide only. Fit can vary depending on body proportions, garment design, fabric, stretch, foot shape, shoe width, construction and personal preference. Where an individual BLOCH product carries its own sizing recommendation, that model-specific advice should take priority.

Best For Jazz • Hip Hop • Commercial • Irish Dance Practice • Dance Fitness • Workshops • Multi-Style Training

Description

The Bloch S0538 Children's Boost Dance Trainers are made for young dancers who need more from their trainers. Supportive, cushioned and exceptionally versatile, they combine the protection of a substantial dance sneaker with the flexibility children need for proper studio movement.

From jazz and commercial to hip hop and Irish dance practice, Boost is one of our favourite choices for busy young dancers whose training doesn't fit neatly into just one style.

Made for Growing Dancers Who Do a Bit of Everything

Unlike an ordinary sports trainer, Boost is designed specifically around dance movement. The split sole allows the foot to flex and articulate more naturally, while the dedicated spin spot beneath the forefoot helps young dancers turn and pivot without a conventional rubber sole gripping excessively against the studio floor.

There's plenty of protection underneath too. An D.R.T cushioned heel and compression-moulded EVA sock liner help soften repeated impact, making Boost particularly useful for energetic classes involving jumps, travelling movement and longer rehearsal sessions.

Built-in arch support and elevation create a more supportive feeling through the middle of the foot, while the adjustable lacing allows the trainer to be secured comfortably around different foot shapes.

We stock Boost in Black – an easy, practical choice across a wide range of dance classes. If your child's dance school specifies a particular trainer or shoe style, always check their uniform requirements before ordering.

Guide

Why Choose Dance Trainers Instead of Regular Trainers?

Everyday trainers are designed mainly for walking, running and forward movement. Their rubber soles can create too much resistance when dancers need to turn, pivot or change direction quickly.

Boost is designed differently. Its split dance sole allows greater movement through the foot, while the dedicated spin spot helps reduce resistance during turns. At the same time, the cushioned heel and supportive construction provide considerably more impact protection than a minimal jazz shoe.

For young dancers taking energetic jazz, commercial, hip hop or mixed dance classes, this combination can make Boost a particularly useful studio trainer.

Dance World Tip

Don't judge Boost by how stiff it looks in your hand. It is a much more substantial shoe than a jazz shoe, but the split underneath is what allows the foot to articulate. Once laced securely, ask your child to point, rise through the foot and try a few dance movements rather than judging the flexibility from standing alone.

How Should Children's Bloch Boost Trainers Fit?

Boost is known for fitting small, so don't simply order your child's usual trainer or school-shoe size.

Always measure your child's feet first. Everyday shoes often already contain growing room, so using that size as the starting point can accidentally add extra allowance twice.

Start approximately 1–1½ UK sizes above the measured foot
Comfortable dance fit with sensible growing room

For a narrower foot or a child who prefers a closer fit, start towards 1 size up. For a broader foot or where a little more growing room is needed, 1½ sizes up may be more suitable.

Quick fit check: Lace both shoes securely and ask your child to walk, rise onto the balls of the feet and try a few dance movements. There should be comfortable toe room, but the heel should remain secure and the foot shouldn't slide backwards and forwards inside the trainer.

Dance World Size Guide is intended as a helpful starting point. Every child's feet are different, so the best size can vary with foot shape, width, socks, growth and preferred fit.

A little growing room is useful; a trainer that's moving independently from the foot isn't. If you're between sizes, prioritise a secure heel and instep while leaving comfortable space for the toes.
