{"type":"firestarter.listing","listing":{"id":"lst_dSvUCSA5","product_name":"Lowell Derby - Men´s","category":"Casual Shoe","description":"A modern classic.\nThe Lowell Derbies in full-grain leather bring a fresh perspective to a timeless profile. A refined apron toe adds subtle structure, while a boat shoe-inspired collar along the quarters lends a quiet maritime influence without straying from its derby roots. The upper offers rich depth and develops a distinctive patina over time, and hand-finished edges sharpen the profile. With its comfortable open-lacing design, and substantial sole, the Lowell moves effortlessly from the office to weekend plans.\nThis product is made from full-grain calfskin leather sourced from a Gold-Rated tannery based in Arzignano, Italy. Being the highest level of recognition awarded by the Leather Working Group, a Gold rating signifies the leather manufacturer meets the most stringent criteria and demonstrates a strong commitment to mitigating its environmental impact.","images":["https://cdn.shopify.com/s/files/1/0175/8496/files/color_tan_2_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_tan_1_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_tan_3_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_tan_4_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_tan_5_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_oak_1_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_oak_2_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_oak_3_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_oak_4_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_oak_5_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_1_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_2_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_3_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_4_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_5_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_bordeaux_1_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_bordeaux_2_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_bordeaux_3_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_bordeaux_4_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_bordeaux_5_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_1_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_2_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_3_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_4_lowell_derbies.jpg?v=1773875584","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_5_lowell_derbies.jpg?v=1773875584"],"price":239,"currency":"USD","in_stock":true,"inventory_qty":599940,"dynamic_pricing":false,"listed_at":"2026-06-20T14:55:46.138Z"},"share_url":"https://firestarter.network/l/lst_dSvUCSA5","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
