I have a pair of Salomon Speedcross trail shoes, like sex for the feet..I sell boots for a living as part of my job in a camping store, Altbergs are great but there's equally good brands. As Rob said, the type walking you're looking to do will influence what boots are best. Merrell are really good value for money if you're looking for all-round mesh boots. Salomon are my personal favourite though, but they get pretty pricey. Scarpa, Meindl, Haix, Berghaus, etc... are all very good too, but everything is situational dependent.
They're amazingly light too, really good footwear. I've got a pair of their Quest 4D boots. I hadn't worn them in over a year and put them on for a lockdown wonder the other day. They made my walking shoes seem inadequate in comparison!I have a pair of Salomon Speedcross trail shoes, like sex for the feet..
