Word to the wise: if your feet fail, your mission soon follows.

I had the original version of the enduro soles for a military event in June. Lets just say that they were shot upon its completion, so I bought more of them (LP and the regular) for another similar event in November.

There is a singular, deal-breaking, mind-numbing difference between the old and the new versions. The blue button on the heel was not there in the original versions, which allowed the thermoformable plastic sheet on the bottom to melt slightly into the base board of the boot.

With the addition of the blue cushion, the footbed does not seat firmly, occasionally shifts, and contributes to heel lift while walking under load. In case you are new to this; thats BAD. Heel lift in this case causes blunt force trauma to your heels every time you take a step, because your heel slams into the insole, regardless of how soft it is.

Take a look at other insole reviews I am writing. Hopefully they are of some value.
