Shoe Recommendations Based on Common Needs/Injuries

The next table illustrates how I would recommend shoes based on his needs or injuries: 

(Disclaimer: Running Shoes do not cure injuries but may ease some pain)

Common Needs/Injuries	Recommendation	Rationale
Versatile shoe for all purposes	Firm but cushioned shoes	Enough cushion for longer runs but responsive and lightweight for faster runs
Plantar Fasciitis/ Achilles Tendonitis	Shoes with a high heel to toe drop 10-12mm	Higher drop shoes take some pressure of the Plantar Fascia/Achilles Tendon
Shin Splints (Medial)	Stability shoes with stability posts or guide rails	Stability shoes reduce pronation by a small amount by guiding the foot into a more neutral position which may relieve pain
Racing shoes for a Half Marathon	Shoes below 230grams while being cushioned	Racing shoes need to be light for easier leg turnover and need to be cushioned enough to protect the legs from the pavement pounding over a half marathon
