Keepz. Save your seams.

Tired of ruining the seams of your favourite pants by permanently stepping on the seams? Fear no more! The keepz keep the fringes ouf your trouser legs away from your heels.
*** UPDATE
While trying them out I found that the keepz could use a little more 'bite' on the trousers part, so I gave them some teeth to get a better grip to the seams. Now they wont let go as easily even while riding my bicycle. A little change on the inner part makes the fit tighter to shoe as well.
