An assembly and a method for determining a temperature distribution of a foot.

The invention relates to an assembly and method for determining a temperature distribution of a foot. The assembly comprises: - a mat comprising a surface for receiving at least part of a plantar surface of the foot, wherein a temperature distribution of the surface of the mat is locally changeable by the plantar surface, and - a thermal imaging apparatus comprising a detector responsive to infrared radiation and configured for acquiring 10 a thermal image of at least the surface of the mat. The method uses the thermal imaging apparatus of the assembly to acquire a thermal image of a thermal footprint left on the surface of the mat of the assembly by at least part of a plantar surface of the foot. The thermal image 15 provides a map or image that substantially corresponds to the temperature distribution. of at least jpart of the jplantar surface of the foot.
