I had very good experience with omniwheels as Idle wheels in a differential drive robot. I have a 10kg robot with some smaller omniwheels and it just works perfect. Normally these wheels are used for transport systems in the industry, but they are perfect for robots too.

This type of wheel takes no extra space when the robot is turning and they look really cool too. I got 8 for 46$ at Kornylak . Order RW10 OMNI 2.580 the diameter is 8cm and remember that you have get 2 pcs. to form 1 wheel. They fit together as you can see on the photo.
