For acro, the sock choice is traction or barefoot. The Alpha Shock is a half-sole with traction up front, so it stays connected to the marley through your landings while 20-30 mmHg graduated compression backs the arch. The Joule Shock runs the other way. It is an open-toe, open-heel sleeve that leaves the foot free to point and splay, with no traction and the ball and heel bare to the mat. Both carry the same arch support, so you are picking the feel and nothing else.
The Alpha Shock carries a 4.72-star average across 270+ reviews and brings the traction. The Joule Shock is the barefoot sleeve dancers reach for when they want no traction at all.
The Alpha Shock and Joule Shock share the same 20-30 mmHg graduated compression, so the arch stays supported whether you take traction or a barefoot feel.
The traction pair covers the front of the foot with an open heel. The Joule Shock is a sleeve that wraps the arch and leaves the ball and the heel open.
Only the Alpha comes with traction, an adhesive grip at the ball that you refresh over time. The Joule skips it by design, so your skin meets the mat at the ball and heel.
Both run XS through XL. Check your shoe size against the size chart before you order so the sock sits true.
The Alpha Shock is the traction pair, a half-sole with grip at the ball for landings on marley, with graduated compression behind the arch. Choose the With Traction build on the product page.

The Joule Shock is the open-heel, open-toe sleeve. It leaves the toes and heel free, so a barefoot pass still feels barefoot, with patented arch support the whole way.

Check the rule sheet before you order a traction sock for a routine that is judged barefoot. Competitions and syllabus exams each set their own line on what is allowed on the feet, and a traction half-sole can fall on the footwear side of that line. When the sheet says barefoot, the Joule Shock keeps you inside that line, an open sleeve with no traction that keeps the arch supported.
Class is a different question, and the floor answers it. Marley collects dust, a hot studio adds sweat, and that pairing is what makes the case for the Alpha Shock With Traction, because the sole stays put on a floor that has gone slick. Mats, carpet, and any floor that already feels tacky go the other way: Apolla’s traction guide puts them on the Non-Traction list, so take the Alpha in Non-Traction or the Joule there. Both come from the Dancer Footwear collection at $38 a pair.
You can tumble in socks, and the right pair moves with you instead of fighting you. An acro pass is a fast chain of jumps, handsprings, and turns, and the foot has to point, splay, and land free every time. An open heel leaves the back of the foot uncovered, and the sleeve frees the toes too, so nothing bunches or catches mid-pass while graduated compression holds the arch from the run-up through the landing.
Sort your passes by the floor they land on, not the shape they end in. On marley, take the Alpha Shock With Traction: the grip sits under the ball of the foot only, so it holds a punch or a rebound and still lets a slide or a split travel. When the rule sheet calls for barefoot, or the floor is a clean mat, the Joule Shock keeps the arch supported with no traction under the sole.
Acro is a short list of shapes drilled over and over. A cartwheel throws weight sideways over one hand then the other. A round-off punches both feet at once at the exit. A front walkover presses through one leg and asks the other to reach overhead. A back walkover reverses it out of a bridge. A handstand parks the body over the wrists and palms while the feet do nothing but stay long. Aerials skip the hand plant entirely.
Group them by what the sole is doing. Some shapes push off through the sole: cartwheel entries, round-off punches, handspring rebounds. Others hold the sole still while the arch shapes itself: bridges, needles, chest rolls, elbow stands. A single routine strings both kinds together, which is why the floor under the pass, not the shape, picks the sock.
Bridge to backbend, backbend to walkover, walkover to limber, limber to handspring, then valdez and aerial work once a spotter steps back. Each rung adds another moment where one leg carries the whole body, which is the moment arch support matters most.
Progressions run on repetition, twenty entries in a session rather than three big passes. Strength drills add more of it, wrists and ankles first, shapes second. A sleeve that stays put through that volume beats one you keep pulling back into place, so size it against the size chart rather than guessing between two.
The pair built to stay connected. Refreshable sole traction holds the marley through landings and turns, the open heel keeps the back of the foot free, and 20-30 mmHg graduated compression sits behind the arch while you tumble. On the product page, choose the With Traction option.

The pick for dancers who want the ground and nothing else. The toe and the heel stay open, so the foot keeps its full range through every pass, with patented arch support and 20-30 mmHg graduated compression doing the quiet work.
Shop Joule ShockWith no shoe in the picture, an acro sock has to earn its place. Both Shocks bring 20-30 mmHg graduated compression and patented arch support, the same support whether you take the traction Alpha Shock or the barefoot Joule Shock. The Alpha adds grip where a landing needs it, the Joule keeps the ball and heel open for a barefoot feel, and both hold the arch through a full session. Both are made in the USA and HSA/FSA eligible, so HSA or FSA funds can cover either one.
A half-sole that holds at the ball for punches and rebounds, graduated compression underneath.
A sleeve with an open toe and open heel and no traction, patented arch support built in.
A sleeve that stays put through a whole session of entries starts with the right size, so settle it on the chart first.
The dancer buying guide lines up the full Shock range for other classes and shoes.
Set the traction Alpha Shock next to the barefoot Joule Shock, browse the wider Shock range, and lock your size against the chart first.
Two socks answer the acro question. The half-sole to hold the floor, or the sleeve to go barefoot.
A summer intensive stacks acro days back to back, so bring enough pairs to rotate. The dance intensives guide lays out how many to pack.
When the day moves from the acro mat to tap shoes, the fit changes, and the tap guide covers what to wear inside a laced shoe.
Acro and turns share the Alpha pick, but the job changes. The guide for turns weighs the Non-Traction and With-Traction builds for spins on the ball of the foot.
Wear a sock the toes can point and splay in, then choose it by the surface. On marley coated in dust in a hot studio, the Alpha Shock With Traction holds through a landing. On a clean mat, or wherever the sheet you compete under says barefoot, the open Joule Shock sleeve is the pick. The Dancer Footwear collection carries both at $38 a pair.
Only where the rule sheet allows them. Each competition and syllabus exam draws its own footwear line, and a half-sole with grip can count as footwear in a routine judged barefoot. If the sheet says nothing about socks, ask the event before the day rather than at check-in. Where grip is allowed, the Alpha Shock With Traction is the acro pick for landings on marley. Where it is not, the Joule Shock's open sleeve keeps skin on the floor and still gives arch support.
Yes. The Joule Shock is an open-toe, open-heel sleeve, so the foot points, splays, and lands as if it were barefoot while the arch still gets 20-30 mmHg graduated support. It is the pick when you want skin on the mat. The traction Alpha is the pick if you would rather hold the floor on landings.
No. Apolla's traction guide puts mats on the Non-Traction list, along with carpet and floors that already feel tacky, so on a mat take the Alpha Shock in Non-Traction or the Joule Shock, which has no traction at all. Save the Alpha With Traction for marley, where dust and a hot studio turn the floor slick. Its grip sits only at the ball of the foot, so a slide or a split still travels.
Acro dancers should wear an open-heel compression sock that moves with the foot. The Alpha Shock, a half-sole gripping at the ball, stays connected on landings and turns. The Joule Shock is a barefoot sleeve with the toe and heel open, keeping a barefoot feel with no traction. Both use 20-30 mmHg graduated compression with patented arch support. Check the size chart before ordering so the sock fits true.
Take the traction pair to hold the marley or the barefoot Joule to go the other way, and let the sock carry the session. 7,300+ reviews stand behind Apolla, and every order ships with the 30-day pain-free trial.
