This is something that no doubt a parent will be tempted to do. With good reason, at a younger age a kid’s foot can always be changing, so buying footwear can be a costly proposition. However, some experts feel that it’s not a good idea to do this, because the pair of shoes has been conformed to the other child’s foot. However, there are also experts who say it’s alright to buy shoes that are second-hand. The best course of action is to see if the shoes actually fit the feet of the younger sibling and that they are comfortable on the child’s foot.
