Healix Care insoles all feature BambooTecc, a natural anti-microbial top cover made from a bend of traditional fibres with all natural nano-bamboo particles. This provides an anti-odour and eco-friendly fibre with high working properties. Thin and comfortable, Healix Care has created both a light and thin shock absorbing inner layer with minimal weight and bulk. The vented design allows heat and moisture to move away from the foot over a wider area, keeping your feet fresh! All insoles are designed to easily fit into most footwear and can be trimmed for a more personalised fit.
