Table 5. Frontal plane back foot (B1-B4) and front foot (F1-F2) golf shoe outer sole design features illustrated in Figure 9. B1 Medial forefoot moulding to facilitate forefoot anticlockwise rotation onto the toe during the follow-through. The moulding incorporates traction groves to provided stability during this stage of the swing process. B2 Wider lateral sole edge providing shoe support during the backswing. B3 Medial forefoot raised oval moulding allowing the natural anticlockwise rotation of the forefoot during the follow-through. The moulding incorporates a single spike to stabilise the forefoot position.Mouldings surrounding the oval moulding prevent any linear slipping during the rotational movement. B4 Angled spikes opposing the medial/lateral and anterior/posterior forces.More spikes located on the lateral edge to provided traction during the backswing. F1 Wider supported lateral sole edge providing shoe support and preventing the shoe buckling during the downswing and follow-through. F2 Angled spikes opposing the medial/lateral and anterior/posterior forces.More spikes located on the lateral edge to provided traction during the downswing/follow-through
