There are a lot of moisturizing options, so do you have to use foot cream to soothe dry, cracked feet? Yes and no. If you want to buy one do-it-all moisturizer and use it on all your dry body parts (including your feet) you'll still be better off than not using any moisturizer at all. However, lotions, balms, creams and serums are often specially made with a specific skin area and type in mind. Eye creams, for example, will have ingredients that won't sting the delicate skin under the eyes. It's similar with foot creams. They tend to be thicker than body lotions, and many contain ingredients that can penetrate thick soles like other moisturizers can't.
