The black Blundstone 510 men's Chelsea boots feature a premium leather upper. Durable boots feature a removable XRD technology insole for shock absorption and to reduce impact on feet and joints. Polyurethane midsole for extra comfort. Thermo urethane outsole is highly resistant to hydrolysis and microbial attack and offer grip on any surface. Tough boots are oil, acid and organic fat resistant. Ergonomically engineered toe spring reduces fatigue. Gussets on both sides for easy slip on and off.
I have been wearing Blundies for many years, and these are my fourth pair. excellent quality, and so comfortable. They are now the only footwear I have that I can wear all day and all night and walk for miles. The soles are extraordinary. I once stood on a red hot horse shoe that my farrier had laid on the ground. I eventually felt a strange pain in my heel, realised what I was standing on and assumed the boot sole would be ruined. In fact it was unmarked and unharmed.
