Place shoes in a delicates bag (pro tip: a pillowcase works too). Choose a gentle cycle with cold water & mild detergent. Shake out any excess water & set aside to air dry. Shoes will regain their original shape with one or two wears. For a full refresh experience, swap in a new insole and laces. Handy tips: Don’t put them in the dryer. They’ll go back to their original shape in no time. You can hand wash your laces and insoles on their own. Onceit sources product globally. Onceit displays a strikethrough price based on the Manufacturer's Recommended Selling Price (MRSP) or recommended retail price (RRP) to show a price comparison. The discount percentage reflects the difference between Onceit's selling price and the MRSP or RRP. Suppliers provide these prices as either the official price set by the retailer or brand, which may vary between different retailers and regions or the price they recommend for sale. While we require suppliers to provide evidence of an RRP or MRSP, the product may not have been sold at that price before or recently in New Zealand. NZD RRP or MRSP is provided by the supplier or calculated by using the market spot rate at time of listing, we use this as the strikethrough price and calculate the discount percentage based on the difference between this price and Onceit’s selling price.
