THOUSANDS OFFREE FEET

Valencia, Spain
“I've been training with the BLACK for 6 months and they've completely changed the way I run. I feel the ground like never before and my times have improved. The best sandal for running, no question about it.”
Carlos Mendoza
Architect
Barcelona, Spain
“As an architect I spend hours on site and at client visits. The OBSIDIAN combine the style I need in meetings with the comfort to walk a construction site all day. Perfect for my lifestyle.”
Marcos Fernandez
Physiotherapist
Madrid, Spain
“I recommend the DÜNE to almost all my patients. The natural footstrike they provide activates the foot muscles and reduces load on knees and back. I wear them myself daily and the difference is huge.”
Diego Ruiz
Engineer
Seville, Spain
“The BLACK are my go-to sandal. The minimalist black design goes with everything and the construction is solid as a rock. 10 months later they're still like new. Pure Spanish engineering.”
Pablo Garcia
Chef
Bilbao, Spain
“In the kitchen I spend 10 hours on my feet. Since switching to the ROMAN, leg and back fatigue has dropped dramatically. My coworkers don't understand how I hold up so long during service.”
Roberto Silva
Entrepreneur
Granada, Spain
“I was looking for a sandal that conveyed style without sacrificing comfort. The OBSIDIAN are exactly that. I wear them both to business meetings and the gym. The craftsmanship and finish are on another level.”
