Type of Application: Whether it be sprays, powders, pods, or bags, the type of shoe deodorizer essentially depends on personal preferences. Sprays are great because they can be used for a wide array of other applications. Powders are great because the are super absorbent and sometimes good for actual application to your own feet. Pods and bags are great because they are made to take in and absorb odor, so you know there's at least no scent masking going on with something as tangible as an actual pod or bag.
Versatility: Sometimes it's easier to buy a shoe deodorizer that can also be used for many other applications. A good spray can be a do-it-all option to remove odor from your shoes to your fitness equipment. The only caveat to opting for versatility is you might sacrifice some effectiveness. There are a few dedicated shoe deodorizers out there that are excellent at tackling heavy odors, and so if you're dealing with a powerful funk it might be best to focus on a deodorizer that only attacks shoes (and feet).
Natural Ingredients: There are a few shoe deodorizers out there that are made with natural ingredients and essential oils. These products are great because they are safe for skin contact and can give buyers a peace of mind if they leave the deodorizer sitting around in a house—this is especially important for parents and pet owners. Another thing to consider about shoe deodorizers made from natural ingredients is the product can sometimes work as a foot deodorizer and be used for direct contact to your feet.
