buy them. i love mine. im on my second pair. i wore the heels off the first pair but they lasted a year and a half of abuse. still keep them around incase my regular ones are wet.
while youre at labonvilles buy the limmer boot grease. its from a NH company that makes hiking boots. keep the grease slathered right to them.
i have the 2" logger heels with the kevlar in them. i dont even know the kevlar is there. the tounge is a little stiff when youre breaking them in, after that they are comfy as slippers. the grease will help with the break in process.
you can also get the grease straight from the manufacturer. just google 'limmer boot grease' it will show up.
