Abstract: The present invention provides an apparatus for acquiring data for designing a last capable of accurately measuring a three-dimensional shape of a sole of a foot that is curved as if a footwear is being worn thereon. The apparatus for acquiring data for designing a last includes a placement section 2 for placing feet F and F? thereon and an imaging means 3 arranged around the placement section 2. The placement section 2 includes a heel rest 12 for placing the heel of the foot F or the foot F? thereon, thereby enabling accurate measurement of the data of the sole that is curved in such a state as if footwear having a heel such as a pump is being worn thereon, without moving the foot during the measurement.
