Replica designer sneakers are imitation versions of high-end designer shoes, designed to look nearly identical to the originals but are produced and sold at a much lower cost. These replicas are not authorized by the original brand and are often made to replicate the appearance, logos, and style details of popular designer brands like Nike, Adidas, Balenciaga, Gucci, or Louis Vuitton, among others. The quality of replica sneakers can vary widely. Some are made with high-quality materials and careful attention to detail, aiming to mimic the original product closely. Others might use cheaper materials and have noticeable differences in stitching, logos, and general craftsmanship.

Replicas are usually significantly cheaper than authentic designer sneakers. This affordability makes them attractive to people who want a designer look without the high price. The production and sale of replica sneakers are generally considered illegal because they often infringe on trademarks and intellectual property rights. Additionally, ethical concerns arise regarding counterfeiting practices and the potential impact on labor standards and quality.

They may also be called "counterfeit" sneakers, though some sellers label their products as "reps" or "replicas" to differentiate from low-quality knock-offs. Some sellers even specify terms like "1:1 replicas," implying that the replica matches the original as closely as possible. Despite legal and ethical concerns, the market for replica sneakers is large. Some enthusiasts even collect them for their novelty, and a community exists that reviews and rates different replicas based on how closely they resemble the originals. While some people see replica sneakers as a way to get designer looks at a fraction of the cost, others avoid them due to quality and ethical concerns.
