Saw these for the first time in person. The spike sections are a little more aggressive and firm than what I thought they would be. I would wear these but still hoping for a predominately gray colorway.
I went into my local GG to size on the Puma Phantomcat Nitro in hopes of ordering the tastefully inspired Masters edition of the shoe and found that they are very uncomfortable -- too stiff. I walk the course and this would never work for me
