Only from optical find the shoes absolutely comfortable. As mentioned in the product description the interior not fed - no problem with an insole and at the price no wonder. Since I find that the shoes be a little large to fit now by the sole perfect (contrary to other recessions say that the shoes would be small). Also, I could not tell the unpleasant odor. Only alone the closure requires some practice. I personally have always bit afraid to make that break - but so far everything seems fine.
