Sole & Signature Touches: The branded Vibram VI-Lite full tread sole and heel is lightweight and flexible, with dependable grip in all weathers. Signature John White branding to the heel sock and sole waist adds a discreet finishing detail.

Also available in pull-up calf as the Byrne Chelsea Boot and in calf suede as the Byrne Chelsea Suede Boot. Frequently Asked Questions Do the Byrne Chelsea Boots run true to size? Yes, they run true to UK sizing. Chelsea boots generally fit close to the foot, so if you're between sizes or have a wider foot, sizing up half a size gives a more comfortable fit, especially with the natural calf leather lining which offers little stretch. What leather are these made from, and are they fully lined? The upper is full grain calf leather, which means it retains the hide's natural surface texture, more character and better durability than corrected grain. Inside, both the lining and insole are natural calf leather, so they breathe well and mould to the foot over time. Can I wear these to the office and also more casual settings? Yes, the Byrne works well across both. The classic Chelsea silhouette pairs cleanly with tailored trousers or a suit, while the Vibram VI-Lite sole and grainy texture give them enough ruggedness to hold their own with dark jeans or moleskin at weekends. How should I care for full grain calf leather to keep it in good condition? Brush off dirt after each wear, then condition every few weeks with a good quality leather cream to keep the grain supple and prevent drying. Full grain leather ages well and develops a natural patina, regular conditioning will deepen the colour over time rather than masking it.
