Look at those spikes on the Custom Caulk Logger 🤯 The spikes (caulks) on our Caulk Logger Boot provide traction in the most treacherous conditions. The tall logger heel provides balance and support while the 8-9oz leather holds your foot and ankle in place. The Great Terrain Equalizer. We don’t mess around with this boot. #jkboots #caulks #spikes #loggerboots | JK Boots
