Orthopedic insole

Abstract

The invention relates generally to an orthopedic insole arrangement comprising a bottom insole ( 110 ), a top insole ( 112 ) and a set of overload tactile feedback elements, e.g. pins ( 115, 116, 117, 118, 119 ) forming an orthopedic insole kit. The assembled insole arrangement gives a tactile overload feedback to patients during rehabilitation, such as during walking, allowing an optimised healing process. The insole ( 913 ) may comprise a bottom insole ( 110 ) having at least one hole ( 120, 130, 140, 150, 160, 165, 170, 175, 180, 185 ), and a top insole ( 112 ) with matching hole/s ( 121, 131, 141, 151, 161, 166, 171, 176, 181, 186 ), wherein at least one pin ( 115, 116, 117, 118, 119 ) is installed to slide vertically inside the hole ( 121, 131, 141, 151, 161, 166, 171, 176, 181, 186 ), thereby protruding from the insole ( 913 ) at some compression of the insole ( 913 ).
