A kind of presser feet back machine of integrated molding, includes a clamping part, which is the barred body of a length； It is a thick and solid position at the top of the retaining part what, section is in rectangle, can be convenient for users to fixed shank position； One moulding portion； The lower section of the moulding position what clamping part, it is in w type that longitudinal direction is prolonged slightly in the front in the moulding portion, which is from top to bottom sequentially one first protrusion, a recess portion, the second protrusion and preceding acies. Length of the rough equal whats people leg of the length in the moulding portion to sole, the ankle of the rough corresponding what people leg of the size and shape of first protrusion； The rough corresponding what foot Hou of the shape of the recess portion with； The bow portion that the rough corresponding what sole of the kenel of second protrusion inside contracts； The preceding acies can substantially place the toe of people at plane with what. The presser feet back machine of this creation meets the foot of ergonomics by radian, and it can be trained for a long time, the foot of dancer is trained with what, to enable the curve of its foot that beautiful appearance is presented, when may make dancer formally to enter the court to perform, beautiful curve radian can be showed at any time.一種一體成型之壓腳背機，包含一夾持部，該夾持部為一長之棒體；該夾持部位於頂部，為一厚實部位，其截面呈長方型，可方便使用者固定小腿部位；一塑形部；該塑形部位於夾持部之下方，該塑形部的正面延縱方向略呈w型，該部位正面由上而下依序為一第一凸部、一凹部、第二凸部以及前緣端。該塑形部的長度約略等於人腿至腳底的長度，該第一凸部的大小及形狀約略對應於人腿之腳踝；該凹部的形狀約略對應於腳後跟；該第二凸部的型態約略對應於腳底內縮之弓部；該前緣端大致成平面可用於放置人之腳趾。本創作之壓腳背機符合人體工學的腳部依靠弧度，並且可以長時間進行訓練，用於訓練舞者的腳部，以令其腳部的曲線呈現美麗的外觀，可使得舞者正式上場表演時，可以隨時呈現出美麗的曲線弧度。
