Product Features:
Soft and Flexible - Exceptionally soft, flexible uppers and soles along with padded heel collars and adjustable insoles
Heel Cushion Technology - Stock absorbing cushions on each heel protect against impact and distribute pressure throughout the foot
Flex Zone - Dual density outsole is built to flex at all the right points, yet still offer the stability and support needed to ensure natural foot motion

Flex Fit System:
Each pair comes with an additional 2mm insole to customize the fit so that it's just the right size for each  child. If a child starts with both insoles( the one in the shoe and the additional insole), as the child's feet frow, the added insole can be removed to extend the length of wear for the shoes.
