Socks for yoga teachers split into two jobs: one for the demonstration, one for the rest of the hour. A yoga teacher may show a pose for thirty seconds and then spend the rest of the hour walking the room and adjusting, so the sock has to do both jobs. The Joule Shock does: open at both ends, so bare skin meets the mat front and back when you demonstrate, with 20-30 mmHg compression around the arch and ankle while you walk. The AMP Shock is the closed no-show you put on between rooms, traction optional for wood floors.
Joule Shock and AMP Shock: patented arch support, 20-30 mmHg compression, two coverages, one of them open-toe and open-heel; the yoga collection carries the APMA Seal.

When you show the pose, your students watch your feet. The Joule Shock leaves those parts uncovered.
Your students hold the pose. You walk the room and adjust a hip for most of the hour; that is the part the arch support is for.
The AMP Shock is the sock you put on in the hallway, built with or without traction.
Both fit snug on purpose, and both size by street shoe size, each style on its own chart.
Open-toe and open-heel, so the open ends meet the mat when you show the pose, with support around the arch for the walking that follows.

The closed no-show you change into in the hallway. Choose it with traction for wood or laminate floors, non-traction for carpet.

When you demonstrate, your feet are the lesson. Students watch where your heel lands and how your toes spread, and a sock that covers them changes what they see. When you are not demonstrating, which is most of the hour, you are walking the room, kneeling beside a student, and standing at the front on a floor built for mats, not feet.
Those are two different jobs, and two Shocks split them. Our yoga socks collection answers the practitioner's question of what to wear on the mat; this answer covers the teacher's feet in the hours around it. The collection's third pick, the half-sole Alpha Shock, puts traction under the forefoot for grounded balance poses; a teaching day asks for open or closed, not half.
With the Joule Shock, yes. It is open at the toe and open at the heel, so your toes and heel are still on the mat. What it adds is arch and ankle compression at 20-30 mmHg, with Apolla's patented support, the support that matters when you have walked two classes and are about to show a warrior sequence for the third.
The Joule Shock has no traction layer. Your own skin at the toe and heel is the grip. That makes it the demonstrating choice, and the wrong one for a hallway between rooms: a hallway floor is hard, cold, and not a mat, and an open sleeve puts your bare heel and toes on it.
The AMP Shock, because a hallway floor is hard and cold, and the Joule Shock leaves your heel and toes uncovered on it. The AMP Shock is a true no-show, closed at both ends, with 20-30 mmHg graduated compression and the same patented arch support. It goes on when the last student leaves, stays on down the hallway and through a class you teach from the front without demonstrating, and comes off when the next demonstration calls for the Joule Shock or bare feet.
Choose it with traction if your studio has wood or laminate floors. That traction sits under the ball of the foot and the heel, arrives sticky, breaks in over a few classes, and can be re-stuck to the level you like. On carpet or an already-sticky floor, the non-traction build is the quieter choice. Either way, check your size once on the size chart.
Send them to the practitioner answer, not the teacher one. A student on the mat for one class is choosing for the practice itself, and the yoga socks collection answers that directly. Your pair is chosen around the walking and adjusting they never see.

The closed no-show you change into between rooms. 20-30 mmHg graduated compression, patented arch support, and a traction build for wood floors.
Shop the AMP ShockBoth are HSA/FSA eligible with no prescription required, so a benefits card can cover both pairs, and both are made in the USA.
Toes and heel: the Joule Shock is an open-toe, open-heel sleeve, so students see bare skin at both ends; the sleeve holds the arch and ankle.
The whole foot: the AMP Shock is a closed no-show with 20-30 mmHg graduated compression.
Under the ball and heel on the AMP Shock; none on the Joule Shock.
Patented arch support on the Joule Shock and the AMP Shock alike, and both are Made in USA and HSA/FSA eligible.
Ones that leave toes and heel uncovered. The Joule Shock is open-toe and open-heel, so students watching see bare toes and heel, while 20-30 mmHg compression and patented arch support carry the arch through the walking and adjusting around it. It stays on for the laps of the room between poses, too.
The AMP Shock, and the reason is the hallway floor: hard, cold, and not a mat, which is exactly where an open-toe, open-heel sleeve leaves skin exposed. It is a closed no-show, graduated at 20-30 mmHg with patented arch support, so the walk to the next room plus the class taught from the front get a covered foot.
Traction for wood or laminate studio floors, non-traction for carpet or an already-sticky floor. The AMP Shock comes in both builds, with its grip at the forefoot and heel. The Joule Shock carries no traction at all; your bare skin at the open ends is the grip.
Send them to the yoga socks collection, which answers the practice itself rather than the teaching day. The one fact any student or gift-buyer needs first is that Apolla sizes by street shoe size, so the size chart settles the order before anything else does.
Choose two socks for yoga teachers: one to demonstrate in and one to teach in. Demonstrate in the Joule Shock, open at the toe and heel so they stay on the mat, and change into the AMP Shock, a closed no-show with an optional traction build, for the hallway and the next room. Both carry patented arch support and 20-30 mmHg compression, graduated on the AMP Shock. Size by your shoe.
Open to demonstrate in, closed for the hallway, sized by your shoe.
