Hi doctors, all day long wearing shoes and i can't not to because i am at uni from 8 am till 12 midnight. how to get rid of smell (other than tea bag method)?

Foot powder: Anti-fungal foot powder and drying your shoes overnight helps a bit, check for excessive sweating and may need a rx for that.

Smelly Feet: Growth of the bacteria in your shoes, socks & skin can cause odor. Try to wash & dry your feet 2-3 times a day. Take a change of socks with you to work. Better take a change of socks & shoes to work and change during work hours. Try to not wear the same shoes every day - rotate them so that there is time to dry out in between wearing. Foot powders help. If this does not work see your podiatrist.

Consider using: The combination of moisture and bacteria creates the smell. Consider changing to "wicking" socks. You can usually find these at the running stores. This type of sock draws the water away from your skin. Disinfect your shoes with spray. Change shoes daily. Also, see a podiatrist. Prescription remedies like topical formaldehyde and/or Botox to control the sweating that may be option.
