Description

The Sergio Grasso Lione (article F23100) is a laced field boot from Sergio Grasso's Michel Robert range. We have the last pairs in stock.

Sized by EU shoe size plus a Sergio Grasso height/calf fit code (for example 38 / HE), so measure both height and calf before you order.

Product Care

Leather: wipe off dust and sweat after each ride. Once dry and clean, apply a thin layer of Sergio Grasso Boot Cream or a quality conditioner. Avoid oily products, which over-soften leather.
Laces: loosen them fully before pulling the boot on or off.
Storage: keep in a dry, ventilated place with boot trees inside to hold the shaft upright.

Step 1 — How to measure

Wear the riding breeches and socks you normally use when taking your measurements.

Calf: While standing, measure the widest point of your calf. Keep the tape horizontal and comfortably snug—not too tight or too loose.
Height: Stand with your leg slightly bent. Measure from the floor to the highest point of the lower leg (the crease behind the knee).
Allow for settling: Add 1–1.5 cm (approximately 3/8–5/8 inch) to your measured height, as the boot will lower with wear.

Step 2 — Select your EU shoe size

Choose your EU shoe size to view the corresponding Sergio Grasso boot-fit codes. The official chart lists boot height first and calf circumference second. Match both measurements and confirm the appropriate fitting code before ordering.
