I cut them off. Bergfahrten fühlen sich identisch an Flachetappen. I walked over 40 miles in these during a visit to Italy. On future rides, if I run into an issue, I will update the review, but for now, I am totally satisfied. I think maybe a decorative shelf would better serve this shelf, as it is truly beautiful! Have stopped me getting blisters on my heels. Now that it is set I love this lock and highly recommend it. Provides great protection (pretty sturdy). customer service was really kind and eager to rectify the situation. Es para niño de hasta 12 años más o menos.
