The shoes I wear for 10 years mainly Dockers boat shoes with thick soles, but not "by Gerli" whatever that means, and I am very pleased with comfort and durability partially 4-5 years 2 pairs alternates all spring / summer and possibly even fall.
These Dockers also not disappoint me. Rein climbing (a small bisßchen too large so rather 44.5) and feel good. I have at Dockers always 44 the 100% fit, they are actually still good for thick socks or a heel pad well. 43 but would be too small ..
The leather and the whole shoe look well made from the seams inspire confidence and the comfort is, apart from the somewhat rigid sole, which roll when not running very smoothly, Dockers typically very good. One feels in these shoes as in a castle. If you still see the price of just under 36 incl. Free delivery, with the possibility for free return if not satisfied, is / was an offer which you should comply quickly.
As for durability, I can not say much, maybe in 4-5 years of the final report which I hope ;-) my purchased at a local shoe retailer winter boots 59.90 rain after 8 weeks were totally soaked and the sole came off. Now I have money on, because I had returned the other (for cash refund) and further attempts to buy cheap plastic shoes, gave up.
In this respect, one must also the price of just 36 euros to see, which is actually 6 star value.
