Overview
Pushing a button stretches the boot of this Roller Derby quad skate through a range of sizes, so a child does not outgrow it quickly. A hinged shell and padded washable liner give support, and buckles replace laces.
Quick-fit buckles let children put them on without help, and urethane wheels give grip for rink and pavement. The limitation is that sizing runs in two ranges, so a child near the edge of a size band needs the other size.
Who it's for
Parents buying a first pair for a child who will grow soon can adjust the fit instead of buying again. Teens and adults, or kids at the top of the Medium range, should choose the Large or another style.
Pros and cons
- Push-button size adjustment
- Washable padded liner
- Buckles replace laces
- Urethane wheels grip indoors and out
- Medium covers a narrow size band
- Warranty limited to a short term
- Chassis material not listed
Performance notes
The boot extends in steps with the push of a button, so toe room grows with the child. Real trucks pivot the wheels for controlled turns, and urethane wheels with carbon bearings roll smoothly over both rink floors and pavement.
