I'm currently waiting on the word from a contracting agency about a new job that will require me to walk around pretty much all day, and occasionally do a little running (just short distances). The dress daily will be khaki or earth-toned tactical pants and a polo. I have previously owned a pair of Merrell Jungle Mocs in the sand color that fit the bill perfectly, but was wondering if you guys had any suggestions for alternative options that might fit the bill.
