I recently bought a pair of the Korker Chrome boots. I was nervous about the lacing system . It took a while for me adapt to the Boa lacing system but once I did I like it very much. The boots are lighter than the Simms G3 boot but the Simms boot keeps my feet warmer in the winter . I don't know why. I wore out the felt soles on my Simms boot in one year ( about 153 days of fishing). When I wear out the soles on the Korkers I will replace them for $30.00 for a new pair of studded felt soles . That is a lot cheaper than 180.00 for a new pair of wading boots. I have the studded felt soles which seem to perform very well. The question for me is will these boots stand the test of time in the water.
