Should I buy crock's

I recently purchased a pair of brown mammoth crock's. the shoe's are nice and and cozy although my feet tend to sweat if I wear them for to long. I like the idea that the wool like lining is removeable because being white they do tend to get a bit dirty but this removeal thing is easier said than done. Everytime I want to wash it I feel like i'm going to pull the little tab like buttons off.It would also be nice to have a wider variety of colors like the originals. Who says winter shoe's have to be dreary looking? It's bleak enough outside let's put some color into our shoes. It would also be nice to be able to buy replacements for the inside'swhen washing them is not doing the job anymore seeing that it's white, or just for a change of color. I would not hesitate to buy another pair since they are cozy and reasonably priced .
