Used Clothes, after all, are the recycling of used and/or unwanted clothes, including Used Summer Clothes and Used Winter Clothes, and this reciprocal buy/sell/trade transaction between the customer and the retailer saves an incalculable amount of unwanted clothing from dumps and landfills.
Used Shoes are often priced significantly lower than brand new styles, even with little to no wear.
Buying used kicks can be a good way to build up a sneaker collection for less cost. Often times brand new pairs of a sneaker simply aren't available anymore. When building up a collection often one wants to add some heat into the mix, which may involve picking up older pairs that have become hard to find. If you want certain specific pairs, getting used sneakers might still be the only option.
