I ordered a pair of these and a pair of yellow Tretorn Skerry rain boots because I couldn't choose without trying them on and seeing them "in person".  I wear a size 8 shoe, have 60-year old feet who appreciate support, and most of all: comfort.

My adorable yellow Tretorns arrived first.
Easy to slip into,
incredibly cute,
plenty of calf room, and
relatively comfortable,
very roomy inside, and
the length was perfect.

I thought these would be the one.

The Sloggers also stole my heart for their fun-good looks.
Easy to slip into,
incredibly cute,
plenty of calf room, and
far more comfortable for my foot, and
the length was perfect.

What I prefer about the Sloggers is that they are designed with more of a "real" shoe style in regards to the boots' curve about the foot bed, with a small and elevated heel.  Plenty of good traction grooves on the sole as well.

We live on a tree farm and just had a rain.  I took them out for a walk and felt secure in my step (more than the Tretorns).  Because I appreciate foot and ankle support for any kind of slippage, the Sloggers win.

The Tretorns are a classic (short) rain boot and if I were going into town on a rainy night for dinner and wanted "a look" and to keep my feet dry, these would be perfect.  But so would the Sloggers.  And since I really only "need" one pair of rain boots...the Tretorns are going back.

Thanks, as always, to Amazon.com for their fabulous Prime service, their generous return policy, and for providing a reluctant store shopper most of what she needs and wants!!
