The foot support includes a flexible top layer, a base layer, and a sidewall connected to edge regions of said top and base layers. Said foot support further includes a cavity defined between said top and base layers, which extend about a forward pocket of said support and which contains a flowable gel, the flowable gel facilitating the adaption of the flexible top layer to the sole of a foot for support thereof. The forward pocket is located in the region to support the transverse arch of a foot and is able to receive a support medium to facilitate adjustable support of the transverse arch.
