Via Francigena Blister Prevention & Foot Care Guide

Blisters end more pilgrimages than any other injury. The good news: they are almost entirely preventable. The Via Francigena's mix of hot tarmac, Alpine descents and long flat stages is hard on feet — but a few habits will keep you walking all the way to Rome.

Footwear

• Trail-running shoes, not heavy boots. Lighter, more breathable, faster-drying. Boots only for snowy Alpine stages.
• A half-size up. Feet swell on long days; tight shoes cause blisters and black nails.
• Break them in for at least 50 km before departure. Never start in brand-new shoes.

Socks

• Merino wool, seamless. The single best blister prevention per dollar. Bring 2–3 pairs and rotate them.
• No cotton. Cotton holds moisture and rubs; merino wicks and stays dry.
• Liner socks (a thin inner pair) reduce friction further for blister-prone walkers.

The daily routine

• Stop at the first sign of a hot spot. A 30-second fix now saves a week of pain. Don't "walk it off" — a hot spot becomes a blister in an hour.
• Tape preventively on known trouble spots. Leukotape P or Compeed over the heel, ball of foot, or any toe that has blistered before.
• Let feet air at every break. Take off shoes and socks at lunch — dry feet are happy feet.
• Clip toenails short and straight. Long nails hit the shoe front on descents and cause black nails.

The foot-care kit

Carry a small kit — it weighs 100 g and saves pilgrimages:

• Compeed or similar hydrocolloid blister plasters (5–8)
• Leukotape P (a small roll) — the gold standard for taping hot spots
• Small scissors or nail clippers
• Antiseptic wipes
• Vaseline or anti-chafe balm — apply to thighs, underarms and feet each morning to prevent friction
• Ibuprofen for inflammation if a blister develops

If a blister develops

Stop. Clean it. If it's small and intact, leave the skin on and cover with Compeed. If it's large or torn, drain it with a sterilised pin, leave the skin as a natural dressing, cover with Compeed and tape. Reduce your distance the next day, or take a rest day — a blister ignored becomes an infection that ends the walk.

The bigger picture

Blisters are a sign something is wrong — shoes too tight, socks too damp, distance too high. Fix the cause, not just the blister. Read the Training Guide and use the planner to keep early days short while your feet toughen.
