Allegedly supposed to be good for 3 1/2. The cracked shelf is still usable but that is not the point. Ive walked miles in these shoes - My dog and I cover at least 3-5 miles daily and often more and these are my go to summer shoes so they endure well and stay nice looking for the life of the shoe as the fabric neither fades nor frays. Since we hung this up we have had a much tidier house and our dogs have been a lot less trouble so we are very pleased with our purchase. Its that Im not use to feeling the arch of the shoe yet. Otherwise it would be have great. This one totally worth the money, the only issue I have with this product is the hook. Do not get a review from a seller, get reviews from purchasers. The Sennheiser?s look more elegant with the steel and leather materials when off the head or when on the head from a side view. Only complaints are that it is dated.
