The Sea To Summit Ultra Flex Bootie is built on the legacy of their original, low profile, sensitive Flex Bootie. They have updated their newest booties and added an incredibly secure closure system, whilst retaining the high sensitivity that makes this bootie a favourite. Sticking lines have been optimised to prevent chaffing from foot straps. The rubber laminated sole gives all the protection you need while also maintaining the best flex for ultimate comfort.

Suitable for kayaking, stand up paddling, surfing, rafting, windsurfing, kite boarding, sailing, and on the reef. The perfect all round aqua shoe. 

Bootie sizes are under specifications and are unisex.

The Booties run small for the size, it is advisable to consider buying the next size up. For instance, if you typically wear a size 8, we would recommend purchasing a size 9.

Size Chart

To find out which size you need, we have prepared a simple method to measure your feet, then convert this into the correct bootie size. Please follow the instructions below and check the table for sizing.

1. Measure your foot. Put a piece of paper on a flat surface. Stand on the paper and trace around the perimeter of your foot with a pencil.
2. Measure the length of the outline. Measure from the farthest part at the back to the farthest part at the front; you can do this in inches or centimeters.
3. Measure the width of the outline. Measure from the farthest part at the left to the farthest part at the right; this will usually be at the ball of your foot.
4. Compare these measurements against the chart. For instance, if the outline measured 26 cm long x 10 cm wide, the men's bootie size would be 7 and the women's bootie size would be 8.5 (this would be a really snug fit).
5. Adjust the size depending on use. If you are using the booties for performance sports, use the size you just calculated. For recreational or wetsuit use, go up a size.

Frequently Asked Questions

Easy to slip on / easy to clean?
As with a wetsuit, a silicone spray (such as Gear Aid Pure Silicone Spray) can help your feet to slide into the booties. Gear Aid Odor Eliminator or Grangers Odour Eliminator will help keep them fresh. 

Meant to be tight?
"Because they are designed for performance sports, the booties are sized to fit snugly. For less technical/recreational use, go up one size (as the sizing chart suggests). "

Suitable for rough or rocky surfaces?
No. The thin, flexible soles are designed to provide contact to performance watersports gear such as kiteboards. They do not provide the cushioning or protection you would need for walking on rocks or gravel.
