| Heel Height | A measure of the vertical distance from heel to ground | Affects pressure distribution and calf strain | Heel fatigue, forefoot pressure | 1: High heel >4inches; 3: Mid heel between 3 to 4inches; 5: Low heel >3 inches | 1 = Painful, too high; 3 = Manageable; 5 = Balanced, supportive |
| Heel Incline | The angle of steepness of the midsole relative to the heel height. It accounts for the slope with/out forefoot pressure | Influences posture and arch tension | Arch strain, foot sliding | 1: >90 degrees; 3: 75-90 degrees; 5:<75 degrees.Typical heels are between 50-75 degrees | 1 = Feels unnatural; 3 = Slight strain; 5 = Feels seamless |
| Heel Shape | Geometric design of the heel | Affects stability,weight distribution, and balance | Ankle wobble, instability | 1: slim style heels; 3: block style heels; 5: Flat wide heels | 1 = Wobbly; 3 = Stable on flat surfaces; 5 = Stable across all terrain |
| Toe Box Width | Horizontal width across toes | Constriction can cause pinching or nerve pain (e.g.,bunions) | Numbness, pressure points | 1: Narrow fit; 3: Standard fit; 5: Wide spacious fit | 1 = Cramped; 3 = Tight but tolerable; 5 = Spacious iwth no pressure |
| Toe Box Girth | A measure of the vertical and volumetric toe area | Impacts volumetric fit | Pinching, circulation issues | 1: Tight compression fit; 3: Standard snug fit; 5: Relaxed volumetric fit | 1 = Squeezing; 3 = Snug; 5 = Comfortable with room for swelling |
| Midcup Sole | The inner lining that supports the arch and midfoot | Affects arch support and energy return | Arch fatigue, foot collapse | 1: Flat unsupported base; 3: Moderate contour support; 5: Full ergonomic contour | 1 = No support; 3 = Moderate; 5 = Full contoured support |
| Midsole Cushion | The cushioning layer between insole and outsole | Absorbs impact and reduces walking fatigue | Foot pain after prolonged wear | 1: Hard dense sole; 3: Moderate cushioning; 5: Premium soft cushioning | 1 = Hard no cushion; 3 = Moderate; 5 = Premium cushioning |
| Arch Support | Structural support for the arch of the foot | Distributes weight and reduces strain | Plantar pain, arch collapse | 1: No arch structure; 3: Partial support; 5: Full ergonomic arch support | 1 = None; 3 = Moderate; 5 = Full ergonomic support |
| Flexibility | The bend capacity of the shoe sole | Affects natural gait and toe movement | Stiff gait, toe restriction | 1: Rigid sole structure; 3: Moderate flex movement; 5: Highly flexible natural movement | 1 = Rigid; 3 = Some flex; 5 = Naturally flexible |
| Breathability | The ability of the shoe material to allow airflow | Regulates temperature and moisture | Sweating, odour, discomfort | 1: No airflow materials; 3: Moderate ventilation; 5: Highly breathable construction | 1 = No airflow; 3 = Moderate; 5 = Highly breathable |
