The foot model has been built based on the extacting data with Solidworks. Then the stress conditions of human foot have been conducted on analysis with finite element software Abaqus .Through the analysis when standing and under rolling pressure. The results show that when adult male standing, the maximum stress and deformation is at the metatarsal, and the stress is 0.919 MPa, the deformation is 1.19 mm;When human foot under rolling pressure of 100N, the maximum stress at the metatarsal is 2.635MPa, When human foot under rolling pressure of 1000N, the maximum stress at the metatarsal is 23.572MPa.the Conclusions have been drawn ：When human feet suffer rolling, the metatarsal is easily injury.
