Small update. I just weighed 1 boot each. Red Wing Iron Rangers: 1lb 12oz Nicks Rangers: 2lb 11oz. So the Nicks are substantially heavier (almost a full lb heavier for each boot). This is not necessarily an issue but the support/comfort has to make up for the added weight. I wouldn't walk around all day in flip flops simply because they were lighter. I will know in a few months.
