Each module snaps into the socket magnetically, and its fool proof to insert/remove each piece. It wasn’t even worth pulling it apart piece by piece! They look great, clean easily and even when my feet swell a little towards the end of the day I can still slip them on without trouble. Beautiful shoes that fit well and look exactly like the picture. It’s a great product once installed makes no noise no rattles etc. Just waiting to see how the stiching will hold up. The sticks are stiff without being too stiff, and the cotton stays in a tight shape. These canvas cuties have laces for area to be widened or tightened but do not require tying. Sound quality is exactly what one would expect from Audio Technica (solid) Very solid build quality.
