In shoes I wear anywhere from a 6 to 7. I ordered a size 7 boot and they fit perfect with everyday socks or thick wool socks. They are sticky in fast moving rivers standing on slime covered logs, drain quickly out of water, and are very comfortable to walk 1/2 mile to a fishing hole. They are light compared to many other boots I tried on and very durable.
I bought these boots to wear with the Redington Willow Waders, which are also well worth it. I had rubber hip boots last year to fish in Northern Michigan lakes and rivers. They were heavy, bulky to walk in, and often cold during spring and fall fishing.
The Redington Willow River products are well worth the money. These are cut for women and fit very well, where other products I've tried lack the fit for a womens body. Also as I am not a fan of the color pink, nothing about these are pink as with most other womens specific products :) Thumbs Up Redington, I will be a repeat customer.
