No matter how much I took, in my short life, boots for fishing, nothing completely suits me. I will not say how to glue and how many sizes should be taken more. Just boot protectors, developed in institutes that are far from the coast. Probably none of the developers climbed on the clay on the banks. The main thing in the tread is that it does not slip and that dirt is easily removed from the sole. All boots cannot stand these criteria. For rubber of the car – wear resistance, support area, removal of water and dirt at speed, etc. For fishing boots, the main thing, in addition to heat, is that they do not slip when descending, ascending and do not keep kilograms of dirt in the soles. Everyone had to wash while going home. He himself fell face down into the mud when he went up to the shore. Both hands were busy. I thought for a long time, took a sharp knife and straightened the protector of my boots in half an hour. Just be careful not to cut the main sole.
