First Endurance EFS Drink Mix is light and easy to digest, and we find you can drink it again and again without getting sick of it, or having stomach issues. It provides the ideal blend of carbohydrates, amino acids, antioxidants, and electrolytes to fuel your working muscles and improve your endurance capacity during exercise. This drink mix uses a combination of glucose and sucrose, which helps increase absorption and utilization during exercise. Not to mention, it’s a 7% carbohydrate solution so it’s low concentration enough to reduce risk of stomach issues.

EFS Drink Mix also uses patented sources of calcium and magnesium, both of which are critical for proper muscle contraction and to neutralize stomach acid and reduce gastric distress. EFS Drink Mix is also unique in that it contains Malic acid, a naturally occurring substance found in many fruits, especially apples and pears. Research suggests that it may help boost performance by promoting energy production and fighting fatigue.

EFS is the solution to cramping. Using the latest amino acid technology, superior mineral bioavailability, and the addition of Malic acid, EFS drinks refuel and rehydrate better than ever before. It has a unique Total Electrolyte Blend that provides the highest electrolyte content available (1160mg of all 5 essential electrolytes per serving), so you won’t need to add anything else to this mix. It is made with no artificial flavors, sweeteners, or colors and is 100% vegan.

Best Sandal Ever
There is nothing about these that I don't LOVE. These are so comfortable and look so good. I have 6 pairs in every color. They r my absolute favorite. Run true to size. Listen to Amazon about sizing. They know... I am between size 7 and 7.5 and they recommended 7 and it was a perfect fit. I have not had any issues with the Velcro closure. Amazon has the best prices for UGGS.

Sandals that go with just about everything.
As a lover of everything Ugg, these didn't disappoint. They are some of the most comfortable shoes I have, very lightweight, and go with just about everything. They remind me of the old school Dr. Martens and I had a massive collection of those in high school. I have worn them quite a bit and you can barely tell as they are holding up extremely well.

Cute and comfortable!
Size: 6.5, Color: Chestnut
These are cute and surprisingly comfortable! My arches feel supported and the soles don’t feel as block-like as other platform style sandals! Things to note: The footbed liner is not made of suede and is a little slippery. It’s like a neoprene liner which was unexpected for an Ugg shoe. Also, I only intend to wear these sandals as slides (a la Birkenstocks) so the “adjustable” Velcro strap over the top part of the foot seems useless. It doesn’t snug the top down at all, functionally speaking it is only to wear around the back of the ankle. Maybe this matters to someone thinking they could tighten the top down a bit. The ankle strap is comfortable but could be a bit longer. Overall they are a cute option to the platform Birks that are very uncomfortable imo. Love the options to order half sizes. I’m usually a 6 in Ugg boots but ordered my regular shoe size 6.5 and they fit well. My heel would be at the very end of my sandal if I sized down. True to size. Keeping and will order in another color!
