Love them or hate them, wellies and horses just go together. It used to be that they were either black or green, and gave you cold, wet feet. Nowadays, that's no longer the case.
Traditional
Traditional wellies are what most people start off with. They are rubber, with no technical features, and for this reason are the cheapest option. Right at the bottom of the budger option are black and green wellies, but there is now a huge selection of bightly coloured and design covered wellies, covered in anything from stars and stripes to floral patterns. The advantage of these is that they are cheap, and can be replaces every year if necessary.
Country Boots
These are usually made from leather rather than rubber, but have been treated to make them waterproof. They more care than ordinary wellies, especially if you want to keep them looking good, and won't cope with the sort of punishment you might give to a pair of cheap wellies. They do look good though, and if you look after them, can last for years.
Wellies for Riding
Ordinary wellies arn't designed for riding, and can be dangerous if you do ride in them. This is because they generally don't fit the foot snuggly, don't have a heel which means they could slip through the stirrup, and if they're wide, can get jammed in the stirrup. But there are wellies made specially for riding that have a footbed disigned to work in a stirrup, and a heel. They are usually lined so keep your feet warm, even when riding. Not having to change footwear beteen yard work and riding can be a godsend, especially when the weather is bad.
Ultra wellies
These are expensive, and the up-market range of riding wellies, desgined for riding and keeping your feet warm, but not sweating. They tend to tailor the boot to your leg, which stops slipping, and come with adjustable straps, buckles and zips. They are perhaps more of a boot than a welly, but can also be used around the yard.
