Dog Boots

Is it better for dogs to wear dog boots and light jackets waterproof walking mountain?
last year i went up Ben Nevis with him and he had nothing in (natural) and he does amazing – much better than me, but could those cool mountain boots and jackets for dogs improve performance and comfort or is it just a waste of money?
The reason for the high-tech boots is well to cushion your dog's injuries. dog pads can be very sore and raw from walking on rough terrain, are usually on the tile or carpet, or concrete, so the pills are not hard, like cushions wild animals. As for the vests are made to bring water and essential items for your dog, such as first aid, and a collapsible water dish. I think both of these elements are not only practical, but why do not want your dog is properly equipped? You wear your hiking boots and special equipment package for you, why not your dog? ETA: I forgot to mention the boots also protect the dew claws and front legs of the bush and rough terrain. Do not want to be in the wild and has a broken nail bleeding spray all over the place.
