Long time Birk. I tried out a few other brands that were significantly cheaper, and they were terrible! Well made and true to size! Solution: perhaps getting one size larger than your normal shoe size will allow for the extra room needed for comfort when walking due to the shoe being snug and pushing your toes forward. I do love this thing! The grey shoes fit okay, but they slide off super easily because the elastic material at the top doesnt keep them on. Theyre slightly larger, which may not be ideal if you have small ear canals, but the foam quality is superb and the noise blocking capability is unmatched. The main issue (and reason for 2 stars) is that with the volume all the way up, the sound is so low that I can just barely hear. The racks are sturdy, they mounted easily with adhesive squares that were provided, and fit various jars. I don’t like the shoe laces that came with the shoes.
