Acorn Men's Slouch Boot Slipper Charcoal L

I've worn the original Acorn slipper socks for 30 years. They're warm, comfortable, and last many years. A common place of wear is the top near the toe where after years, they'll wear out. Not an issue because they last for years. I thought moving up to the "Slouch Slipper" sock could refer the original obsolete because the toe area has extra leather. I found the Slouch Slipper foot fit to be just fine, and clearly a bit more support and protection, but the wool knit sock section is way too wide and tends to fit sloppy because of the slouch. To the point that it causes the whole slipper to slide off your feet, despite have the correct foot size. Still like the brand, but next time I go back to the original slipper sock. The more expensive Slouch version is not worth the higher price for the unreliable fit.
