A shoe insole suitable for use in making shoes by the Strobel method comprises a non-woven bonded fibre fabric in which at least 60 % by weight of the insole is polypropylene and the remainder is a polyolefin bonding agent of lower melting point than the polypropylene. A method of making this insole comprises procuring a non-woven fibre web in which at least 5 % by weight of the web is provided by fibres which comprise a bonding agent of lower melting point than polypropylene and the remainder of the fibres comprise polypropylene attaching the web to a polypropylene scrim by needling and subjecting the web the heat whereby to melt the bonding agent thus to bond adjacent polypropylene fibres to one other and thereby form said non-woven bonded fibre fabric.
