Who Are They For?

Ideal for: Intermediate/advanced women runners for 10km-marathon races, women weighing 50-70kg looking for speed, tempo run/interval training at 3:30-4:30/km, sub-3:30-4:00 marathons, training-race versatility, transitioning from traditional to racing shoes, racing budget under €200.

Not recommended for: Absolute beginners (too responsive), severe overpronators (stability shoes needed), ultra races over 42km (max cushion better), slow recovery training (overkill), weight over 75kg (extra cushioning needed), those seeking maximum durability beyond 600km.

Key Technologies

PWRRUN PB: Saucony proprietary foam based on PEBA (polyether block amide). 88% energy return vs 65% standard EVA. Extreme lightness, superior responsiveness, maintains properties up to 500km. Same technology as Endorphin Pro (top-of-the-line).

Nylon SPEEDROLL plate: Stiff nylon plate (vs Pro's carbon). Saucony patented rocker geometry. Natural heel-to-toe propulsion, 4% energy saving (Saucony 2023 study). Less aggressive than carbon, more versatile for training-race.

SPEEDROLL Geometry: Pronounced heel-to-forefoot rocker. Facilitates transition, reduces calf strain, maintains consistent speed. Unique "rolling forward" sensation from Saucony.

Differences Between Endorphin Speed vs Endorphin Pro

• Plate: Speed nylon vs Pro carbon (Pro more responsive +10%)
• Weight: Speed 210g vs Pro 195g (-15g for premium technologies)
• Price: Speed €160 vs Pro €240 (€80 difference)
• Durability: Speed 400-600km vs Pro 300-400km (nylon more durable)
• Use: Speed versatile for training-race, Pro for races/tempo runs only

Is the Pro upgrade worth it? Only for competitive races under 3:00 marathon or if budget allows. For 90% of runners, Speed offers 85% of Pro performance at half the price + superior durability.

Women's Size and Fit Guide

Fit: True to size (regular fit). Snug racing fit but not tight. If between sizes, choose your usual size.

Conversion chart:

• EU 37 = US 6 = UK 4 = CM 23.5
• EU 37.5 = US 6.5 = UK 4.5 = CM 24
• EU 38 = US 7 = UK 5 = CM 24.5
• EU 38.5 = US 7.5 = UK 5.5 = CM 25
• EU 39 = US 8 = UK 6 = CM 25.5
• EU 40 = US 8.5 = UK 6.5 = CM 26
• EU 40.5 = US 9 = UK 7 = CM 26.5

Fit test: Try with thin racing socks. 0.5cm space at the big toe. Heel locked without slipping. Snug midfoot fit without excessive compression.

Racing Training Program

Marathon preparation week (60-70km):

• Tuesday: 12km tempo run at race pace (Endorphin Speed perfect)
• Thursday: 10x1km intervals with 2' recovery (Endorphin Speed ideal)
• Saturday: 25km long run at marathon pace (alternate Speed/cushioned shoes)
• Sunday: 10km-half marathon race (Endorphin Speed racing)

Endorphin Speed cover 60% of quality training + 100% of races. Alternate with cushioned shoes for long/recovery runs (preserves Speed, prevents injuries).

Maintenance and Durability

• Cleaning: Soft brush + cold water. Never machine wash (degrades PWRRUN PB)
• Drying: Natural air for 24h. No radiators/direct sunlight
• Storage: Dry, ventilated place. Untie laces
• Rotation: Use only for quality training/races. Save for maximum performance
• Expected lifespan: 400-600km (PWRRUN PB maintains responsiveness up to 500km, nylon plate more durable than carbon)
• Signs of replacement: Loss of rebound (test: press thumb on midsole, if it doesn't spring back = replace), sole wear over 50%, race times worsening

Comparison with Market Alternatives

Vs Nike Vaporfly 3: Vaporfly ZoomX + carbon (superior responsiveness), weight 195g vs 210g. Vaporfly €260 vs Speed €160 (€100 saving). Speed double durability (600km vs 300km Vaporfly). Speed better value for money.

Vs Adidas Adizero Boston 12: Boston Lightstrike Pro (similar to PWRRUN PB), weight 220g vs 210g. Boston €150 vs Speed €160 (€10 difference). Speed superior SPEEDROLL geometry, Boston more stable.

Vs Hoka Mach 6: Mach PROFLY+ (less responsive than PWRRUN PB), weight 230g vs 210g. Mach €140 vs Speed €160 (€20 difference). Speed superior racing performance, Mach more versatile for daily use.

Frequently Asked Questions

Are they good for a first marathon? Yes, if you already run 10km under 50'. No, if you are an absolute beginner (better cushioned shoes). Speed ideal for sub-4:00 marathons, requires decent running technique.

Can I use them for slow training? Not recommended. SPEEDROLL geometry pushes speed, uncomfortable below 5:00/km. Use cushioned shoes for recovery/slow long runs, Speed only for quality/races.

Difference between nylon vs carbon plate? Nylon: less responsive (-10%), more durable (+50% km), more versatile, less expensive. Carbon: maximum responsiveness, races only, fragile, expensive. Nylon optimal for training-race, carbon for elite competitions only.

How long do they really last? 400-600km with correct use (quality/races only). If also used for slow runs, 300-400km. PWRRUN PB maintains 85% responsiveness up to 500km (superior to Nike's ZoomX which degrades after 300km).

Do I need custom orthotics? No if you have a neutral footstrike. Responsive PWRRUN PB is not compatible with rigid orthotics (they cancel out SPEEDROLL geometry). If overpronation, consider Saucony Guide (stability).
