This stove is very practical, I don't like to cook inside the house that's why I bought it. But you can use it wherever you want

So comfortable!
My fiance uses these daily and still loves them! The memory foam is such a comfortable fit and they are true to their size.

Comfortable but runs large
These flip flops are very comfortable with a soft lightweight footbed that feels great to walk in. The fit is a little big with the footbed being the right size but the straps are way too lose causing me to accidentally kick the shoes off when walking up steps. Overall they are comfortable sporty flip flops but you may want to order a half size down.
