Horseloverz no longer carries the Women's version of the Derby boots so I will leave my review on the Men's because apart from larger sizing they are identical. These boots, while high quality, are impossible to size online. I measured and ordered according to the size chart provided and the boots are so oddly put together that I highly recommend if you are considering purchasing these boots that you do it IN PERSON so that you can try them on. At the very least ORDER A SIZE UP. The calf sizing is accurate but is tight at the top and then for some reason it tapers to a narrow point at the ankle and it does not flex (as other rubber boots do) so it is almost impossible to get your foot into the boot. Finally, the footbed is accurate sizing but if you can't even get your foot past the narrow ankle then what is the point? And if you go up a size then the footbed may be too large. The mesh lining of the boots is also an ugly orange and while it says it is breathable in my experience the material they used holds on to sweat and water so I do not have high hopes for that. Again, the boots are high quality on the outside and they do look fairly waterproof but for the price I would look elsewhere.
