Good for dancers
Color: Lagoon, Style: 2 Blocks
My daughter is an Irish dancer and got these to practice keeping her legs straight. After using for a month we can see a difference. They are sturdy and decent quality. Would give 5 stars but our friends have some that are more comfortable.

Perfect!
Color: Grey, Style: 2 Blocks
Perfect size and very stable and soft. This isn’t cheap and wobbly like some blocks — this is thick and my husband who is 220lbs uses it with no problem! Love it!
