A user-customizable insole for insertion into foot wear in place of a conventional removable insole. The insole includes a cushioning upper insole and a semi-rigid yet resiliently flexible base insole used with insole adjustment devices. The upper insole is made of a resilient cushioning material such as foam. The base insole is made from relatively thin plastic with upwardly formed arch supports defining corresponding elevation curves between the base insole and a foot bed or inside bottom of the footwear to permit downward flexing of the arch supports. The arch supports are of a predetermined flexibility by controlling the material thickness and/or adding perforations therethrough. An upwardly formed perimeter wall extends around a heel portion forwardly along respective medial and lateral sides of the base insole tapering away at about a forefoot portion of the base insole defining a heel cup. The upper and lower insoles may be two-thirds length extending from the heel to the behind the toes of the wearer's foot or of full length extending from the heel to ends of the toes of the wearer's foot. The two-thirds length base insole includes a first metatarsal head extension which extends forwardly to support the first metatarsal head of the wearer's foot. The upper insole and the base insole are affixed together at a mid-portion of each with respective forefoot and heel portions unaffixed to permit access for adjustment devices to be added and removed. The adjustment devices may include a first metatarsal head extension boot, forefoot and heel wedges, resilient arch support pads, heel lifts, and resilient heel cushion pads which are self-sticking to the insoles to adjustably position the wearer's foot within the foot wear.
