I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Great upgrade compared to others
Color: Rechargeable with Storage Stand and Box - Black
This frother is far superior to other hand held versions we’ve owned. The attachments are much sturdier and don’t bend as easily (which made the others we’ve purchased quite useless). Rechargeable battery seems to last longer and provides plenty of power even on the lowest setting. The little wisk easily whips up eggs for a morning omelette and frothing cream and mixing powder into drinks are super easy with the other attachments. Finally, the stand is actually sturdy and balanced enough that it doesn’t easily tip over.

Three froth/blend options, rechargeable, comes with container
Color: Rechargeable with Storage Box - Silver, Color: Rechargeable with Storage Box - Silver
I watch a gentleman online who always talks about how in his 40 years he didn’t know x, y, z, and ends with “ain’t no way.” He made this 3-ingredient — 4 with ice— iced coffee, and used a handheld frother, so after shopping for ingredients, I went in search of a frother. What I liked about this one is that it’s not battery operated, but instead is rechargeable. It comes with three attachment, one of which I can use for cake batter, whipping up eggs, making homemade whipped cream, and also sauces and gravy. It also has a case so I am storing it with my coffee paraphernalia. It has three settings and I used the high setting. As you can see it really froths up the ingredients. I’m very pleased with my purchase and thought about all the times I need a slurry of water and cornstarch to thicken soups and stews. I don’t know the charge life yet, but so far, so good. What you see in the cup is 2 tablespoons of sweetened condensed milk, 3 teaspoons of instant espresso, and 2 ounces of water. Then you add the ice and your creamer, half-and-half, or barista lover’s oat milk, and you’re done. Not too bad, as my grandpa used to say.

Great product
Color: Rechargeable with Storage Box - Black
It’s great! Very powerful, even on low speed. Mixes fiber, and powdered mix-ins very well as well as frothing milk. Nice sturdy little case to keep the components in. Stays charged for a long time.
