●Flexibility v Stiffness
COMFORT
AFL Requirements Player
• Endurance / Balance / Agility / Skill Execution/ speed
• Distance – Midfielder 13km (rotations) / Tall fwd 15km (game time)
Environment

Why Modify Footwear?
• Injury
• Protection
• Load Management
• Surface & Sport Specific
• Improved Fit
• Style / Sponsorship
How Do We Modify Footwear?

Lacing Techniques
Injuries

• Wide Forefoot
• Nerve Compression Neuroma / P&N
• Narrow Heel
Footwear Type
• Conditioning Sessions – Runner
• Preseason Skills – hybrid boot / Trail Runner
• In season – traditional boot
Trail runners v Runners
TRAIL RUNNER
• Stronger outersole, better for side to side activity
• Same level of cushion as runners
• Mesh tighter weave/more durable for kicking
• Aggressive tread better traction/ grip
RUNNER
• Tend to be lighter
• More breathable
• More options in styles and sizes/widths
• High level of cushion better for running
• Less lateral support
Boots v Runners

Stress
Sole Plate ●Studs / Conical Combination
Grip & Release / Comfort Increased Traction/ High Grip
Blades
Combination
Types of Football Boots
PROTECTION/ SUPPORT
Full length cushion midsole
Heel height more like runner 10mm higher pitch
Cushioned heel counter and cup
Removable liner if needed for orthotic fit
Deeper and wider fit
Bigger / Heavy Players
PERFORMANCE/ SPEED
Lower heel height - takes adjusting
Less cushion in base
More aggressive fit - narrower and tighter
Shallower fit, not as easy to fit an orthotic if
needed
Liner not usually removable
Lighter / Quicker Players
Advanced Footwear Modifications
●Heel Lifts / HG10mm - Calf/ Achilles/ Heel
