{"type":"firestarter.listing","listing":{"id":"lst_DB6I6Vjd","product_name":"Lowell Derby - Nubuck - Men´s","category":"Casual Shoe","description":"\nRelaxed form, refined texture. \n\nThe Lowell Derbies lean into texture and ease, offering a more relaxed expression of the classic derby. The velvety nubuck upper introduces a soft, matte character that gives the profile a quiet, lived-in refinement from the first wear. A clean apron toe keeps the profile composed, and a subtle collar along the quarters adds a nautical accent. Constructed with an open-lacing system for natural, adjustable comfort and set on a durable outsole, the Lowell in nubuck adapts easily to your plans.\nThis product is made from supple and sultry nubuck 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_walnut_1_lowell_derbies_nubuck_76e8df93-92c7-4c57-9da4-855cb9e10a65.jpg?v=1773944370","https://cdn.shopify.com/s/files/1/0175/8496/files/color_walnut_2_lowell_derbies_nubuck_2de19699-f526-4966-b69a-cc784eadfbd7.jpg?v=1773944370","https://cdn.shopify.com/s/files/1/0175/8496/files/color_walnut_3_lowell_derbies_nubuck_b037542a-205b-49a0-a085-75cc372e0cf6.jpg?v=1773944370","https://cdn.shopify.com/s/files/1/0175/8496/files/color_walnut_4_lowell_derbies_nubuck_361d0beb-49ac-4f6d-a438-6c8f1d5d6d54.jpg?v=1773944370","https://cdn.shopify.com/s/files/1/0175/8496/files/color_walnut_5_lowell_derbies_nubuck_29d0a393-8917-4e05-840b-a34002c37654.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_1_lowell_derbies_nubuck_800e9e0b-c87f-4c36-abb8-60066faa9a42.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_2_lowell_derbies_nubuck_f1122377-1e59-4b67-9102-f2e74d3b7bbd.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_3_lowell_derbies_nubuck_5b811bb4-82de-45b2-924b-70a6e7f03ec7.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_4_lowell_derbies_nubuck_5cfa31e2-4551-4281-b2af-6ed63bdf69ec.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_brown_5_lowell_derbies_nubuck_3f088fef-6afd-4ab6-be34-0557069b4dd1.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_1_lowell_derbies_nubuck_d40871f2-8b29-4997-8d2c-6162a5785e0b.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_2_lowell_derbies_nubuck_cedaf80c-d042-4ed9-a83b-8e48f2cdc061.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_3_lowell_derbies_nubuck_4d3dc59d-b79f-45e2-875e-9ed604f2c87c.jpg?v=1773944424","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_4_lowell_derbies_nubuck_1be5d689-edf2-4418-bcfc-c486495d0491.jpg?v=1773944370","https://cdn.shopify.com/s/files/1/0175/8496/files/color_black_5_lowell_derbies_nubuck_212f5cfb-5e9e-4fa0-82a9-8be7068b9de3.jpg?v=1773944370"],"price":239,"currency":"USD","in_stock":true,"inventory_qty":359964,"dynamic_pricing":false,"listed_at":"2026-06-20T14:55:46.146Z"},"share_url":"https://firestarter.network/l/lst_DB6I6Vjd","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
