3D shell
The 3D shell is the firm anatomical base of a Sidas insole with a heel cup. It supports the arch, keeps the foot in the correct position and improves stability when walking and during sport.
The Sidas Comfort 3D Junior kids' insoles are lightweight insoles for children's footwear that help keep the foot in the right position during everyday wear and sport. They support the longitudinal arch, seat the heel firmly in the shoe and absorb impact on every step thanks to a softer, flexible material.
Key features
3D shell – an anatomically shaped heel seat and arch support hold the foot in place.
Transverse and longitudinal arch support – softer, lightweight support that helps the foot stay properly aligned.
Comfort foam – a flexible construction allows natural foot movement.
Antibacterial top layer with microperforation – better breathability and a cleaner feel in the shoe.
Softer EVA material – cushions heel strike while staying lightweight.
Trimmable – easily cut to the exact size of the shoe.
Where these insoles fit
The insoles are designed for everyday and sports footwear for children. The manufacturer also recommends them for ice and inline skates, where they can help limit overpronation and support joint alignment. For young football players we have the dedicated Sidas Max Protect Football Junior kids' insoles. For older kids and adults see the Sidas Universal Comfort 3D insoles or the Sidas Cushioning Gel 3D with gel cushioning. You will find more models from Sidas in the insoles category.
