Eczema of the toes can have multiple causes, most likely it is due to the humidity or sweating between the toes if you wear socks and tight shoes for very long.
Next Steps
Make sure you dab and dry the skin between the toes. You can use powder so that there is less humidity and dampness. The local applications will temporarily suppress your complaint but it will not cure.
Health Tips
Change of footwear from time to time in the day will make it better. As and when possible keep your toes dry.
