First ray wipe \/ first met head cutout \u2013 reduces dorsiflexion of the first metatarsal.<\/li>\n<\/ul>\n\n\n\nIn reality, foot structure is not so black and white. There is still weightbearing pressure under the first metatarsal head of a compliant plantarflexed first ray. The first metatarsal can still dorsiflex and the arch flatten a little with a stiff plantarflexed first ray. Plus, there are coexisting biomechanical factors that may impact on the orthotic prescription variables used. The task for your podiatrist is to determine which factors are most relevant and to prescribe an orthotic device (pre-made, customised or custom-made) with the appropriate prescription variables for your foot structure, function and activity.<\/p>\n\n\n\n
Don\u2019t forget repetitions and friction levels<\/h3>\n\n\n\n
Look back at the quick refresher on skin shear. We\u2019ve dealt with pressure and bone movement in the discussion so far. But we\u2019ve assumed the number of shear repetitions and friction levels have remained unchanged. Certainly, you can choose to reduce the number of shear repetitions. But it would mean walking or running shorter distances or less game time. Friction levels are easy to reduce with moisture-management methods, Engo patches, lubricants or powders. There are two further blister prevention strategies your podiatrist may implement. These are: shear absorption, such as with a Spenco orthotic cover; and shear distribution with skin taping techniques.<\/p>\n\n\n\n
Wrapping up<\/h4>\n\n\n\n
When it comes to blisters under the first metatarsal head, a plantarflexed first ray can be significant in different ways. Consider the forces imparted to the overlying skin when the first ray is stiff and compliant.<\/p>\n","protected":false},"excerpt":{"rendered":"
