I am very pleased with this purchase Their small tweaks ultimately do result in a perception of a more natural overall sound. But not even a month of use and theyre basically bald. I wouldn?t recommend these heels if you had to be on your feet a lot. Seither weiß ich Birkenstock mehr denn je zu schätzen. Son loves these, they?re holding up well. Likely just an adjustment I need to make with the shoe laces. The mailman hucked the package out his window, leaving a crater in the box that would rival the South Pole-Aitken. I got them to replace a similar Puma model after 8+ years of use. Classy look, good fit, feel substantial, cool packaging.
