Planter fasciitis is a common cause of heel pain in adults with a major incidence seen in women. Planter fasciitis is frequently seen among athletes playing various sports. However, it is more prevalent in professional runners(1). A list of intrinsic risk factors are associated with this condition which can be linked with individual's anatomy, physiology, their mobility \& function or it can be linked with degenerative changes(2). The Biomechanical stresses including the increase in the intensity, frequency or the time frame of weight bearing activities that subject athlete's feet to continuous impact loads, surfaces with inadequate cushioning or improper shoe replacement are some of extrinsic risk factors associated with planter fasciitis(3). Individuals experiencing PF employ compensatory techniques to lessen pain experienced at the plantar fascia's origin(4). They assume antalgic gait pattern, increasing support on the lateral and anterior faces of the foot to reduce the amount of time their heels are in contact with the ground in return affecting upright posture within the base of support due to these compensations, which alter joint position perception and muscle activations resulting in static and dynamic imbalances(5).3-D ankle mobility exercises are improvised for treatment of plantar fasciitis, these comprise D2 diagonal PNF leg patterns, comprising of flexion-abduction-internal rotation and extension adduction-external rotation(6). To increase coordination, joint range of motion, muscular strength, and eccentric control associated with PF, these exercises can be paired with the combined isotonic (CI) approach. This allows the concentric, eccentric, and stabilizing contractions of agonists to be performed without relaxation(7). Heel drop exercise training is another useful intervention used for treating PF; the protocol consists transferring their body weight onto the forefoot of their dominant legs while slightly flexing their ankles. To get back to baseline, the non-dominant leg is given more weight, and the dominant leg's knee was remained fully extended to maintain higher gastrocnemius activation(8). The heel drop exercise modify Lateral and medial gastrocnemius architectural conditions which has been implicated in patients with PF, resulting in injury prevention(9).The purpose of our study is to determine a comparable exercise regime for planter fasciitis among athletes which can easily be incorporated as an essential component of their routine training program in order to prevent the occurrence of planter fasciitis as well as improve the prognosis of already affected athletes. Planter fasciitis is a common condition prevalent among female athletes, however, frequently ignored as well. The groundwork of this research will help creating awareness among female athletes and provide them with a significant solution to help with the pain which causes a less efficient exercise performance. Very few data is available to support the use of 3-d Ankle mobility exercises. Our investigation will also explore the generic effects of commonly unknown 3-d Ankle Mobility exercises with combined isotonic technique which are based on the D2 diagonal PNF patterns
