Is this shoe waterproof?
No, the Caldera is not waterproof. The waterproof options are the Ghost 10 GXT, Adrenaline 14 ASR and the Cascadia GXT.
What is the Velcro tab on the back of the shoe used for? I've tried searching and can't seem to figure it out. I am new to Brooks. Thanks!
It is for a running gaiter, which is used for trail running to keep water and dirt off your legs.
The integrated Gaiter tab at the heel secures trail running gaiters with a hook and loop.
Does this shoe have a wide toe box? I wear ghost 10 now, is it about the same?
Hi! I would say the Caldera's toe box is about the same as the Ghost 10! Brooks Running
