I used to buy same widest shoes every year when I lived in Houston. Two last years they got shittier, I suddenly needed 2 sizes larger shoe - later I learned they outsourced all production to China - and then sure enough they bankrupted. Well deserved. A company was half century old and what a shameful end.

Didn't find anything comparable ever since, but Sievi is the best I found. They don't have just that wide models, but at least they are sturdy af
