Instantly became my favorite shoes! No breaking in at all and instant comfort. They were the only shoes I brought to Honolulu and wore them for 5 days straight, and my feet were happy! I love the fact that they are closed toed shoes but I do not feel hot or sweaty in them. I did however add an Aldo terry cloth insole to them, so my feet would not stick to the footbed, and adds a little more cushioning. The best part is the outsole, which is fabulous for walking on any type of terrain, as it has a lot of grip, and is super sturdy. If you're traveling in warmer climate and can only bring one pair of shoes, these are it! The reason I'm only giving them 4* instead of 5 is because the memory foam footbed compacts down pretty quickly and does not rebound after the first 2 wearings, making the front much more roomy (maybe even too roomy if you have a thinner foot). I wish they would mix some other types of cushioning in addition to the memory foam layer for a more sustained cushion.Update: May 6, 2017. The memory foam has really packed down to almost non existence, and for the first time I was very uncomfortable walking in them, as the front is so loose and the heel has almost no padding. So I've added a heel pad and it is feeling a lot more comfy now. Will be adding a pad for the front too and see if it will help. There is no excuse for using inferior foam in such an expensive shoe, as the cushioning in all my other shoes are still going strong after way more wearings. Therefore I've deducted a star*I hope you found my review helpful. If so, I would greatly appreciate it if you would click the HELPFUL or YES button. Thanks so much and Happy Shopping! :)
