Fun, Practical, and a Great Value
This set of yoga socks is a great find. You get five pairs in different fun, bright colors, which makes them a lot more fun than standard workout socks. The non-slip bottoms do the job during yoga or Pilates, gripping the floor well, and the toe separators are a good option for toe crowding or scrunching — they help keep everything separated and comfortable.
The design is shaped more like a flat tube, without a defined heel. They’re not uncomfortable, but I think they’d fit better and feel more natural with that extra shaping built in. The fabric is a thin sock material rather than cushioned, so don’t expect a lot of padding.
At about $2 per pair, they’re still an excellent deal. They do what they’re supposed to, they’re lightweight, and the colors make them fun to wear. A few small improvements would make them perfect, but overall I’m really happy with them.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value.
By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference.
Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design.
Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.
