⚪︎ Item 20th Anniversary Model Ai-ya Terroir Collaboration This is a collaboration model with "Ai-ya Terroir," which, like the Spingle, is based in the artisan town of Bingo. The base model is SPM-442. The shoes, which combine smooth cowhide leather and cowhide velour, are dyed after production with indigo to express variations in color depth. "Ai-ya Terroir" handles everything from indigo cultivation to the production of "sukumo" (the dye material) and dyeing. The traditional "natural wood ash fermentation" indigo dyeing, passed down through generations in Japan, creates a deep hue. Please enjoy the unique color of indigo dyeing.
