The lining material in the Nike Ja 1 is a soft, breathable textile fabric, likely a blend of polyester and nylon. This material is used in the inner bootie, around the collar, and the tongue to provide a comfortable, plush feel and wick away some moisture during play.
A good description to use is:
"Soft, breathable textile lining with plush foam padding in the collar and tongue for comfort."
The lining material of the Nike Ja 1 is a synthetic textile fabric, likely a blend of polyester and nylon fibers. This material is used throughout the interior for a snug fit, comfort, and durability. The ankle collar and tongue also incorporate open-cell PU foam (polyurethane sponge foam) for plush, locked-in padding.
In short: the lining is a textile fabric with foam padding.
