Don't pick a number just by your everyday shoes. Try the socks you actually wear by the water, and check if the fingers stay free, and the heel stays steady when walking. If you use neoprene boot socks, their thickness may require a different variant. Take a few steps and squat before making a decision. Check also that the calf is not pressed.
Before you step in, check the hardness of the bottom and the visible obstacles. Do not go so deep that the upper end of the boot approaches the surface, especially in waves or rough terrain. For feeder position on a steep bank, first choose a stable route to the stand, because the long shoe limits the stride more than the low one. In a strong current, stay at a secure depth and don't rely on the shoe for balance.
The overalls are more suitable when you have to go deeper, but the cut should allow free sitting, bending over and working with the landing net. When standing for long periods of time, pay attention to inner comfort, and when moving frequently, pay attention to the freedom of the knees. Do not replace the pitch assessment with higher equipment.
After use, wash away the silt and grit, then dry the boots away from a strong direct heat source. Keep them upright, inspect the folds and inner layer, and before leaving, check that there is no moisture retained. A clean tread is important for a steady step along a slippery shore.
Compared to the feeder fishing spot, the choice of boots or overalls makes sense to consider together with Fishing accessories. Compare it briefly through Boots and overalls; then move on to Clothing and equipment for feeder fishingto put the decision in the context of the rest of the clothing and equipment.
