LOVE these shoes!  I live in Idaho mountains and we have no shortage of mud, dirt etc.  I've been wearing these through snow, slush, mud when I take my dogs hiking and these are great.  They are warm, completely waterproof, great support inside and have excellent traction on the bottom.  I have a very high instep and can get them on/off easy. Plus they are really cute!!!  Very well made and can't beat the price.  I wear a 7/12, got the 8's. I have more than enough room....maybe even the 7's would have fit.
