2. Understanding Normalcy Inverted Everted Normal Bow-leggedKnock-kneed Normal

3. Understanding Normalcy, cont. These are abnormal foot types…a normal or neutral foot type is a happy medium between these two. Pes planus = Flatfoot Pes cavus = High arch foot

4. Best Foot Forward A person who runs properly: A person who runs properly: Lands on heel Lands on heel Foot rolls to ball of toe while turning inward (pronates) Foot rolls to ball of toe while turning inward (pronates) A person who runs flat footed: A person who runs flat footed: Lands on heel AND ball of foot Lands on heel AND ball of foot Foot rolls inward excessively, which also causes the lower leg to turn inward Foot rolls inward excessively, which also causes the lower leg to turn inward A person who runs with a high arch: A person who runs with a high arch: Lands hard on heel Lands hard on heel Doesn’t pronate enough to allow the impact of running to be absorbed through the body Doesn’t pronate enough to allow the impact of running to be absorbed through the body The feet and outer part of knee and hip bear the brunt of each step The feet and outer part of knee and hip bear the brunt of each step

5. The Right Shoe: Basic Qualities How often do you need new shoes? How often do you need new shoes? It depends on how much running you do per week… It depends on how much running you do per week… Ex: Jog 60-70 mi/wk, replace shoes every 3-4 mos Ex: Jog 60-70 mi/wk, replace shoes every 3-4 mos Worn-out shoes (esp if soles are worn down unevenly) can be dangerous Worn-out shoes (esp if soles are worn down unevenly) can be dangerous They don’t provide proper support/stability anymore They don’t provide proper support/stability anymore Be aware of your foot type before purchasing new shoes Be aware of your foot type before purchasing new shoes With all the new shoes available, choosing a shoe is no easy task…this is where running shoe store experts come in!
