Rubbish quality. I bought these Hi Tec Altitude VI boots to replace 30 year old Scarpa boots and they didn’t last 30 weeks haha. The leather has split and fractured all around the sides where the boot flexes as you walk. The sales pitch mentions durability but that must refer to the company’s ability to stay in business selling such poor quality products. These are easily the lowest quality footwear I have ever owned and they were well over $200.
