Product Description
Low Density Arch and Heel Control Insoles for Delicate Feet
Slimflex Comfort Low Density 3/4 Length Orthotic Insoles provide gentle biomechanical support for people who need foot alignment correction but cannot tolerate rigid orthotics.
Made from soft A25 density EVA foam with a brushed nylon top cover, they offer cushioning and structured arch support in a compact orthotic design.
The three-quarter length profile supports the heel and arch while leaving the forefoot free, allowing the orthotic to fit comfortably in a wider range of footwear including dress shoes, work shoes and tighter-fitting everyday footwear.
Designed especially for sensitive or delicate feet, Slimflex Comfort LD helps stabilise the heel, support the arch and reduce strain on the plantar fascia. The softer construction helps disperse pressure while maintaining the orthotic contour needed to guide healthier foot movement.

How they work
Slimflex Comfort LD 3/4 Length works by supporting the heel and arch of the foot with a contoured orthotic shape that helps stabilise the rearfoot and guide natural foot motion.
The deep heel cup improves rearfoot stability while the arch contour fills the gap between the foot and shoe, helping to control excessive inward rolling of the foot. This can reduce strain on the plantar fascia and other soft tissues of the foot.
An integrated first metatarsal cut-out supports the natural windlass mechanism of the foot, helping encourage smoother toe-off during walking while maintaining comfort under the arch.
Unlike simple foam heel inserts, Slimflex Comfort LD combines cushioning with biomechanical structure to provide supportive alignment as well as pressure relief.
