adidas unisex-child Racer Tr21 Running Shoes


Keep your little one on the move in the adidas unisex-child Racer Tr21 running shoes. Designed for active toddlers, these sneakers feature a breathable mesh upper to keep feet cool and comfortable all day. The synthetic outsole provides durable traction perfect for running and playing on various surfaces. And with at least 50% recycled content, these shoes are also environmentally friendly.

Breathable Mesh Upper

The lightweight mesh upper offers maximum breathability to keep your child’s feet cool, dry and comfortable all day long. The open weave construction allows air to freely circulate in and out of the shoe, preventing overheating. Whether your toddler is running around the playground or walking to school, their feet will stay fresh in these well-ventilated sneakers.

Durable Traction Outsole

The adidas Racer Tr21 features a sturdy yet flexible synthetic outsole to provide reliable traction on various surfaces. Shaped tread lugs grip the ground to prevent slips and falls, while also allowing natural flexibility for growing feet. Your child can traverse playground equipment, sprint across grass, and walk down hallways with confidence thanks to the durable grip.

Made with Recycled Materials

adidas designed these toddler shoes with sustainability in mind. The mesh upper contains at least 50% recycled content, diverting plastic waste from landfills and oceans. The recycled polyester helps reduce dependence on virgin resources while also decreasing carbon emissions compared to manufacturing new material. Your child can run, play and explore comfortably knowing their shoes tread lightly on the planet.

Running-Inspired Active Design

Inspired by classic adidas running shoes, the Racer Tr21 promotes an active lifestyle for growing toddlers. The low-profile design provides freedom of movement for little feet to run and climb. An OrthoLite® sockliner cushions every step while also wicking away moisture to prevent odor. Finished with the iconic adidas 3-Stripes on the sides, these shoes will have your little one looking and feeling like a mini marathoner.

Size and Fit

True to size based on toddler foot measurement. Wide sizing accommodates growing feet. Hook and loop closure allows parents to adjust for the perfect snug fit. Measure your child’s foot and use the adidas size chart to find the ideal size. Runs slightly long to allow room for growth.

For the best fit, consider ordering a half size down if your toddler is between sizes. However, allow growing room if your child’s feet are rapidly increasing in size. adidas designs their shoes to promote natural development, so only size down if the shoes are uncomfortably loose, not snug.

Care Instructions

Machine wash cold, gentle cycle. Air dry only. Do not bleach or place in dryer. For stubborn dirt, spot clean with gentle soap and water.

Check shoes regularly for signs of wear, as active toddlers are tough on their footwear. When the outsole tread is worn or the upper mesh is damaged, it’s time to size up and replace with a new pair of adidas Racer Tr21 shoes.

With the right care and sizing, these toddler running shoes will support your child’s active lifestyle through seasons of running, jumping and playing.
