Can you wash insoles

The other day, my Sperry top siders were smelling funky, so I took out their removable insoles, got some normal dishwashing liquid, filled a bin with water and squirted about three spoons of dishwashing liquid in it. Then I let the insoles soak in it for about ten minutes. Afterwards I got a toothbrush (not going to use it afterwards of course), dunked it in the soapy water, then started scrubbing the insoles, removing a lot of dirt and nasty smell. I then took them outside on a sunny day and let them dry for about 8 hours. They were pretty good afterwards.
