At BlackToe Running, we generally do not offer product holds or reservations. Our inventory is constantly changing, and we want to ensure that all customers have equal access to our products. However, we understand that there may be circumstances where an exchange is necessary, and exceptions can be made in those cases. If you have already made a purchase and need to exchange it for a different size or color, we may be able to hold the desired item temporarily while you process the exchange. Please note that holding items for exchanges is subject to availability and our discretion. We recommend reaching out to our customer support team as soon as possible to discuss your specific situation and inquire about the possibility of holding the item for your exchange.
