After choosing your waders and wading boots you need to select other wading accessories. Make sure your waders have a belt as the belt is to keep the water from rushing in through the top of your waders should you slip one.
In most rivers, especially fast flowing rivers, a wading staff is a great way to keep your balance.
Boot studs are also great to stop you from slipping on slippery rocks. There are also several companies that produce universal studs that work with most brands of wading boots. Two of the best are Goat Head Spikes (link to Amazon) and Grip Studs. Both are great options, but if you’re trying to keep costs down, go with Goat Head Spikes.
