This is my first MBT shoe. I had 4 foot surgeries around my big toe joint and I needed a shoe that not only had a roomy toe box but one that could also accommodate my narrow foot. My surgeon and podiatrist both recommended I get rocker bottom soles so ordered these boots. I wore them for the first time last week and they were super comfortable all day, and I got compliments where ever I went. AND I love the rocker bottom sole: it takes the load off my big toe joint by about 70%.
