*Not all that portable. If needed more space than that, you can just buy another an add on top. -Comes with an anti-rattle stabilizer. I have only had them a few weeks. Other than that youll just need to make sure to charge the headset before getting started. It really is a great idea. These shoes were very beautiful and comfortable. My feet actually got colder once I put them on. the variety of wraps offered was terrific! The price is right.
