I hope one of you highly experienced people can help me with what maybe a stupidly obvious question

I run my 1 sib sam with a scooter and on smooth surfaces he runs fine but on the the bits of the tail with small patches of gravel he slows and try to avoid it, this is no problem as he just moves to the side of the trail.. I was wondering though about the use of boots are they for the protection of injuries or can they be used for less sympathetic surfaces.
