A measurement information output system comprises an input unit and an output unit. The input unit is configured to input, to an arithmetic unit, a detected force value indicating the magnitude of force detected by one or more force sensors arranged so as to receive impact by motion of a measurement target and a detected acceleration value indicating the acceleration of the measurement target detected by an acceleration sensor arranged so as to detect the acceleration of the measurement target. The arithmetic unit is configured to compute the weight of the measurement target on the basis of the detected force value and the detected acceleration value. The output unit is configured to output, as a measured weight value, the weight of the measurement target computed by the arithmetic unit.

Provided is a dampness prevention function-equipped insole (50) including an upper layer portion (11) formed in a foot shape, with small holes (4) being formed therein, an intermediate layer portion (51) including tubes (12a) in which air holes (5) are bored at positions corresponding to the small holes (4), the tubes (12a) being installed in a front-rear direction at a front part and a rear part and being installed in a left-right direction in a middle part, and a lower layer portion (13) in which mesh cloth woven in a lattice shape is formed in the foot shape, in which the insole (50) is formed in the foot shape and placed in a shoe in which the upper layer portion (11), the intermediate layer portion (51), and the lower layer portion (13) are sewn such that the tubes (12a) maintain a predetermined interval.

An arch support may include a base plate having a base plate top surface. The arch support may further include a contoured arch plate attached to the base plate at a joint. The arch plate may include an arch plate bottom surface. The arch plate bottom surface may face and be separated from the base plate top surface, with an extent of the separation increasing toward a medial side of the arch support.

An article of footwear includes a sole system with a carrier member and a plurality of sensory node elements. The sensory node elements are received in recesses of the carrier member and can protrude through to the upper and/or an insole. The sensory node elements push against the foot to increase sensory perception of the surface underlying the sole system.

An article of footwear including a sole structure attached to an upper defining an internal void configured to receive a foot of a wearer is described. The sole structure includes a sole body portion having a plurality of sensory node elements located in apertures in the sole body portion. The sensory node elements have a bottom surface configured to contact the ground and move vertically within the apertures. The movement of sensory node element pushes a top surface of the sensory node element attached to a portion of the upper against the foot of the wearer. The sensory node element provides sensory feedback to the foot of the wearer about the condition of the ground. The sensory node elements are arranged at discrete locations across the sole structure to provide sensory feedback at desired portions of the foot of the wearer.

A shoe insole having a protruding portion for stimulating the plantar side of a foot, and both shoe insole surfaces are used. The insole contains: a flat plate-shaped base portion made of a flexible material; and a protruding portion from at least one of the first and second insole surfaces and stimulates the plantar side of a foot. The first and second insole surfaces stimulate the same portion of the right and left feet when a load is applied by the foot from the second surface where the insole is in one of right and left shoes with the first surface having the protruding portion in contact with the shoe mid-sole portion, and when a load is applied by the foot from the first surface where the shoe insole is placed in the other of right and left shoes with the second surface in contact with the mid sole portion.
