TECHNOLOGY

1x drivetrain

A 1x drivetrain means more versatility, simpler shifting and less things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. Everything you need and nothing more.

Just-right geometry

The all-new FX Sport has slightly less reach and slightly more stack than previous models for a more comfortable yet active and fast riding position.

Wide toe box
The color is pretty on these water shoes. The toe box on these shoes is wide which collects water making it difficult to use them walking for exercise in the water. I bought these specifically to keep my feet protected. The sole is the perfect thickness needed but can’t use them for what they were bought for.

Good and affordable
Size: 6-7 Women/5-6 Men, Color: 1a-stripe Black-2
Pretty good and effective for the price! I wore these to volcano bay in Orlando and they got the job done. While these water shoes have great comfort, traction, versatility, and water resistance, they don’t have a lot of support on the sides of the shoe. They also are tight/snug around the ankles. Theyre very lightweight and can bend and fit in a fanny pack or purse, but if you’re looking for a supportive water shoe, these aren’t it. But if you need something to just get the job done so you can have fun, these are it!

Solid and comfy
Size: Medium, Color: Black (001)/Jet Gray
Absolutely love these sports bras. They’re simple and solid, and I love the colors! They do run small, so I’m glad I sized up. I’m usually a small, but got a medium and they fit perfectly. For reference I’m 5’5”, 125lbs, 34B. They wash well too! Just make sure to air dry them and wash on cold only.

Great bra, poor customer service
Size: Medium, Color: Black (001)/Jet Gray
I like this bra. It offers great support. But the sizes run small. I remembered this after placing my order. So I got back with Amazon two times within six hours of placing the order to cancel, so I could exchange it for a larger size. Amazon would not cancel the order. And they have no option for exchanging it. They used to allow 24 hours before processing an order. Not so here.
