Only a change in the price of shoes (in this case, an increase) will cause a movement along the demand curve for shoes. A change in the price of related goods, such as socks, would cause a shift in the demand curve. An increase in income would also cause a shift in the demand curve, as it would result in a higher level of demand at every price point.
