TSA Eliminates Mandatory Shoe Removal at Airport Security

Few rituals in modern travel are as universally recognized and almost universally disliked as the airport shoe removal. Since 2002, domestic travelers at U.S. airports have been required to remove their footwear, place it in a plastic bin, and send it through X-ray screening before collecting it on the other side of the checkpoint. The requirement outlasted its original technical justification by well over a decade, persisting through successive generations of scanning technology that could have rendered it unnecessary far sooner. As of July 2025, the TSA has formally eliminated the mandatory shoe removal requirement at participating checkpoints, ending a protocol that had become one of the most familiar and frustrating features of American air travel.

The elimination is not merely a convenience measure. It reflects a genuine technological transition in how airport security screening works, the same shift toward advanced computed tomography scanning that has also been reshaping European airports' approach to liquids. For travelers, the change reduces friction at checkpoints, cuts processing time, and removes one of the primary sources of hygiene concern in airport security lanes. For the TSA, it represents a meaningful step toward a screening model that relies on technology rather than ritual.

The Rule's Origins and 23-Year Run

The shoe removal requirement traces directly to December 22, 2001, when British national Richard Reid boarded American Airlines Flight 63 from Paris to Miami with explosives concealed in the hollowed-out soles of his high-top shoes. Reid attempted to detonate the device mid-flight but was subdued by passengers and crew before he could do so. The attempted attack was thwarted without the involvement of airport security, which had screened Reid and found nothing of concern.

Despite this, aviation security authorities recognized that existing X-ray equipment was not reliably detecting shoe-concealed explosives. The TSA formalized mandatory shoe screening in 2002, and reinforced it after further analysis of the Reid incident. The logic was straightforward: conventional X-ray produced images of sufficient resolution to detect dense metallic objects but struggled with lower-density materials like the plastic explosive PETN that Reid had used. Removing shoes and placing them flat in a bin produced a cleaner image that improved detection rates.

The problem with this approach was not its underlying logic but the pace of its expiration date. Advanced scanning technology capable of rendering the manual removal unnecessary was commercially available in prototype form by the early 2010s. TSA PreCheck, launched in 2013, exempted enrolled members from the shoe removal requirement as part of its expedited screening protocol, and no security incidents resulted from that decision over the following twelve years. The case for extending the exemption universally was therefore not a new argument but a long-delayed conclusion.

How the New Technology Works

The CT scanners now deployed at major U.S. checkpoints generate three-dimensional volumetric images of scanned items using the same computational tomography principles that medical scanners employ. Unlike flat X-ray images, which require a trained operator to interpret two-dimensional shadow patterns, CT imaging produces a full spatial model of each object's internal structure and material composition.

For footwear, this capability is decisive. A CT scanner can distinguish between the dense rubber or foam layers of a normal shoe sole and the different density profile of an inserted explosive compound. It can identify anomalous voids, embedded objects, or unusual material compositions within the shoe structure without requiring the shoe to be removed from the traveler's foot. The scanning resolution and automated threat-detection algorithms make the physical removal protocol redundant from a detection accuracy standpoint.

The TSA's rollout of the new rule follows the deployment timeline of the CT scanning equipment rather than a calendar-based mandate. Airports and checkpoints that have completed CT scanner installations and passed TSA certification requirements began applying the no-removal standard immediately. Airports operating older X-ray equipment, primarily smaller regional airports and some secondary terminals at larger facilities, continue under the original protocol until their equipment is upgraded.

What to Expect at the Checkpoint

For travelers departing from major U.S. hub airports, the practical checkpoint experience has already changed. Signage at CT-equipped lanes now instructs passengers that shoe removal is not required. Checkpoint staff working these lanes no longer direct travelers to remove footwear as part of the standard preparation process. The checkpoint experience at these facilities now resembles what TSA PreCheck members have experienced since 2013: shoes remain on, laptops may remain in bags (at CT-equipped lanes), and the overall throughput time decreases noticeably.

A point of transition-period caution: the rollout is uneven. At airports with a mix of older X-ray lanes and newer CT lanes operating simultaneously, travelers need to observe which lane type they are entering. At non-CT lanes, the original shoe removal requirement technically remains in effect until those lanes are upgraded. Staff at major airports are generally managing this transition with clear lane-level signage, but travelers who walk directly into a lane without looking at posted instructions risk slowing the queue by requiring a mid-process adjustment.

For travelers who have not yet enrolled in TSA PreCheck, the shoe removal elimination removes one of the most tangible practical differences between standard screening and PreCheck lanes. PreCheck still offers significantly faster throughput for other reasons: dedicated lanes with shorter queues, the ability to keep laptops in bags universally, and no liquids-in-a-bag requirement. But the visual and experiential gap between PreCheck and standard lanes has narrowed with this change.

Implications for Packing and Checkpoint Preparation

The practical packing implications of the shoe removal change are modest but real. Travelers who previously wore slip-on shoes specifically to make the removal process less awkward can now make footwear decisions based on comfort, weather, and destination rather than checkpoint practicality. Lace-up boots, heeled shoes, and complex athletic footwear are no longer penalized at CT-equipped checkpoints.

There is a secondary implication for the contents of personal item bags and carry-ons. The shoe removal ritual created a space beneath the checkpoint conveyor belt that many travelers used as a staging area for repacking after screening. With removal eliminated, that post-checkpoint reorganization step also disappears, further reducing the time from screening completion to gate departure.

For frequent travelers, the shoe rule's elimination is a genuine quality-of-life improvement that compounds across hundreds of annual checkpoint experiences. For occasional travelers navigating the airport with children, mobility aids, or complex footwear, the change removes a source of logistical stress that, while manageable, was always unnecessary given what the technology could accomplish. The TSA has arrived at this point later than the underlying technology required. But it has arrived, and the checkpoint experience for the foreseeable future will be measurably better for it.
