I absolutely love Wildling shoes! They are beautifully crafted, sustainably made. They are very, very comfortable, from the get go, no need to break them in. They are stylish, to boot. I have three pairs of Wildling shoes now, The Tanuki Niji, Cahor, and now most recently, a pair of the new Pertos. When I purchased the Cahor shoes, I wondered if I had purchased the wrong size, yet the length was perfect. I was going to send them back. Then, I thought I would try adding an adhesive heel pad. That made them wearable, so I contacted Wildling again and said that I would be keeping them. Shortly after that, I realized that this might be an issue with foot volume. Anya wrote about foot volume, "What Is Foot Volume? November 16, 2021 A What Is Foot Volume? Foot volume is the amount of vertical space your foot takes up." I highly recommend Anya's reviews. This little article, "What is Foot Volume" has saved the day for me. It seems that these shoes might be constructed for those who have a "higher foot volume" than I do. I decided to order and extra pair of Wildling's insoles. This made a huge difference. Now these shoes fit beautifully. There are a number of solutions to customize your fit, such as heel pads, extra insoles, and tongue pads. So, now I have tools for customizing the way shoes fit. This is worth noting, as everyone's feet are different. The folks at Wildling are gracious, and very, very helpful. I love this company. I think they are a beautiful example of beauty in design, sustainability, collaboration with other forward thinking small businesses, and really stellar customer care.
