BOSCH HCFC5011 1/2 in. x 16 in. x 21 in. SDS-Max SPEEDXTREME Carbide 4-Cutter Rotary Hammer Drill Bit delivers 100% carbide heads with four-cutter design, making them the toughest, long-lasting bits for drilling in reinforced concrete and hard aggregate. The bits provide 5X life vs. competition. The bits are engineered using proprietary diffusion-bonding technology, which bonds carbide and steel at a molecular level. It’s a precise high-heat, high-pressure solid-state welding process that produces jobsite-proven bits. Bosch is the only concrete bit manufacturer to make its own carbide, and 100% quality check on each and every single bit. The bit has a four-cutter design with 180° cutting diameter and 100% power transfer during drilling. The active-centering tip results in rounder hole, while the four 90° side angles create a wide and sharp head keep driving precise holes. The four-flute design aggressively pulls dust away from the work, for fast drilling and longer bit life.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.

I stay on your foot they don’t slip in your shoe

This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!
