I have both the calked and the regular Hoffman's. They are both great boots. For removals the calked boots are great, and you can take 3 calks off and wear spikes as well. They also have different types of calks to choose from and if you buy the calked boots and find out later that you really don't like them you can send them back and they will replace the sole with a regular sole of your choice. They also make the boot custom for you so you can get off sizes, or wide, with or with out shank or steel toe. If you buy them get extra insoles that they sell. They have a web site, check it out.
