The famous i play rubber rainboots that were so worn and loved by my first son have been passed down to his younger brother, and they are just as adored by this child. They are also in remarkably good condition for the amount they’ve been worn.
At the first sign of rain he drags them out, and tries to wear them even when it’s not raining. Of course many times I let him- they’re great for playing in snow and mud, too.
They must be super comfortable, and I’m relieved knowing they are not off gassing any harmful chemicals.
