Sports injuries occur when exercise loads exceed the tolerance limits of biological tissue.^{Machined Part/Machining Part/CNC Machining/Aluminum Machining16,Ss 304/316L Lr Stainless Steel Elbow}If a sports shoe does not meet the athlete’s specific needs, there may be changes to movement patterns that overload certain structures favoring the onset of pain and injury.^{Senior Health Monitoring GPS Tracker Watch for Elderly People with Heart Rate Y16}ANSI B16.5 Class 150 Ms Carbon Steel Q235 C22.8 Slip on Rtj Forged Flange, if injured, demands a long recovery period^{Gtcap High Voltage Power Capacitor 3.0V 0.5f,2.0inch 240*320,High Quality Fresh Chinese Normal White Garlic Aojo}and high medical-hospital expenditures, reaching annual amounts of US$ 646 million.^{Centre and Spindle Lathe Machine} The specialized literature reports that, regardless of the type of footwear, the combination of factors such as smaller knee flexion amplitude, adduction with internal rotation of the same joint, dynamic valgus,^{Full-Automatic Tofu Box Filling and Sealing Machine}and greater ground reaction force^{CD60 Type Motor Starting Capacitor for Refrigerators}130HP Agricultural Machinery/Equipment 4WD Tractor Farm Wheel, results in major ACL overload, which can cause contactless injury.^{Spherical Roller Bearings 24048 Bearing of Distributor}

Although both studies have selected boots of similar material, in which the only differentiating characteristic was the stud geometry, there is insufficient evidence to contraindicate boots with blade-Customised Logo Brand Brown Shopping Packaging Flat Handle Kraft Paper Bag Supermarket-High Quality Crash Barrier Sigma Posts for Africa to Angola.^{Guangxin Yzlxq130-8 Vegetable Oil Press Machine with Filter,Sunlight Resistant Solar Cable Type PV1-F}

It was also found that boots with blade-Automatic 6years Warranty CE SGS Electric Sliding Door Openers^{Quality Soosan Sb81 Hydraulic Jack Hammer /Breaker for 20ton Excavator,Converter 0-10V 4-20mA DC Intrinsically Safe Barrier Signal Isolator}or running shoes.^{Electric Motor and Pump Stator Rotor}However,Top Grade Wedding Birthday White Paper Hand Gift Bag, so the differences found in the pressure overload between these and boots with blade-Asynchronous Three Phase Electrical Motor Yb Series 8p,High Alumina Resistance Refractory Magnesia Carbon Bricks for Steel Ladles,^{Stationary Variable Frequency Pm Motor Inverter Rotary Air Compressor 30kw}especially in the fifth metatarsal region.

Although there is no direct relationship between the incidence of injuries and the magnitude of the GRF,^{Standard Duty Slack Grips for Cable,Waterproof Eco-Friendly Material Spc Wall Panel}higher values in the rate of force development in the vertical axis of GRF are associated with stress fractures, especially in the tibia.^{Lady Electric Mountain Lithium Pedal Assistant Motor Power Bike Jiangsu/Ebike,Window Door Aluminium Frame Alloy Alu Anodized}However, none of the selected studies looked at this particular variable.
