Why your ankle hurts and what desk work and daily habits have to do with it
Nicola Tik

Ankle pain is not the first thing most people associate with desk work. The ankle is not directly involved in typing, mouse use, or screen time in the way the wrists and elbows are, and the connection between a sedentary working day and ankle discomfort is less immediately obvious than for some other areas. But the relationship between how the ankle is loaded, or not loaded, through a desk day and how it feels is genuine and worth understanding, particularly for people who spend significant time sitting and then find their ankle more uncomfortable during or after activity.

What the ankle is and what it depends on

The ankle is a complex joint connecting the lower leg to the foot, designed to manage the significant forces that walking, standing, and activity transmit through it. It allows the foot to move upward and downward, and through a combination of joints in the foot itself, to rotate and adapt to uneven surfaces. The ankle depends on a combination of bony stability, strong ligaments, and the surrounding muscles and tendons to function well under load.

The muscles that control ankle movement are located primarily in the lower leg, with the Achilles tendon, the largest and strongest tendon in the body, connecting the calf muscles at the back of the lower leg to the heel bone. The tendons on the front and sides of the ankle control the upward movement of the foot and its rotational stability. All of these structures are sensitive to both the demands placed on them and the periods between those demands, and a day of sustained sitting followed by a period of activity produces a particular pattern of load that is worth understanding.

What prolonged sitting does to the ankle

During prolonged sitting, the ankle is held in a relatively passive position with little active muscular demand. The calf muscles, which play a central role in pumping blood back up from the lower leg towards the heart during movement, are largely inactive. The tendons surrounding the ankle are not being loaded or moved through their range. And the ankle joint itself is receiving minimal of the varied compression and release that movement provides.

This reduced activity during prolonged sitting has two significant consequences that affect how the ankle feels during and after activity.

The first is a reduction in circulation in the lower leg. The calf muscles act as a circulatory pump during movement, contracting and relaxing with each step and driving blood upward against gravity. During sustained sitting this pump is largely inactive, and blood and fluid tend to pool in the lower leg. Many desk workers notice their ankles and feet feeling puffy, heavy, or slightly swollen after a long sitting session, reflecting this accumulation of fluid that movement would ordinarily prevent.

The second consequence is a reduction in the tendon and tissue readiness for load. The tendons around the ankle, like tendons elsewhere in the body, benefit from regular graduated loading to maintain their resilience and responsiveness. During prolonged sitting they receive almost no loading, which means that when activity resumes, the transition from inactivity to demand is more abrupt than it would be in a more consistently active day. This abrupt transition is one of the reasons that ankle and Achilles tendon discomfort often feels most pronounced at the beginning of activity after a long desk session, gradually easing as the tissues warm up and adapt to the demand.

How footwear and foot position during sitting contribute

The position of the foot and ankle during sitting and the footwear worn through the day both influence how the ankle loads and how comfortable it feels.

Sitting with the feet flat on the floor at a roughly neutral ankle angle tends to be the most comfortable and least provocative position for most people. Feet that are tucked under the chair, crossed at the ankle, or resting on tiptoe for extended periods place the ankle and lower leg in sustained positions that can increase tension in the Achilles tendon and calf muscles and contribute to stiffness and discomfort when standing up and walking.

Footwear choices have a significant effect on ankle load through the day. High heels shorten the calf muscles and Achilles tendon during wear, producing a similar effect to the sustained shortening that prolonged sitting contributes to. Completely flat, unsupportive shoes reduce the cushioning of impact and the support of the arch, increasing the load on the ankle joint and surrounding tendons during walking. A heel height that is modest rather than extreme, in footwear with adequate cushioning and arch support, tends to produce the least cumulative load on the ankle through a day that combines sitting and walking.

How daily activities load the ankle beyond the desk

Several everyday activities outside of the desk environment contribute to the cumulative load on the ankle in ways that are worth being aware of during a period of ankle pain.

Walking surfaces matter. Hard, flat surfaces like office floors and pavements transmit more impact to the ankle than softer or more varied surfaces. During a period of ankle pain, being mindful of the surfaces being walked on and choosing cushioned footwear for harder surfaces reduces the impact load on the joint with each step.

Stairs place a higher demand on the Achilles tendon and calf muscles than flat walking, because the calf has to work eccentrically to control the lowering of the heel on each step down. During a period of Achilles or calf-related ankle pain, descending stairs with care and avoiding prolonged stair climbing reduces this particular loading pattern.

Standing for extended periods places a sustained compressive load on the ankle joint that sitting does not produce, and the transition from a long sitting day to a period of prolonged standing or walking tends to be one of the most provocative patterns for ankle discomfort. Introducing movement gradually after a long sitting session, rather than going directly from sustained sitting to sustained standing or walking, gives the ankle tissues time to adjust to the increase in demand.

Simple adjustments that reduce ankle load through the day

A few practical adjustments tend to make a meaningful difference to how the ankle feels during and after a desk day.

Keeping the feet and ankles gently moving during sitting, through small foot pumps, ankle circles, and occasional calf raises while seated, maintains the circulatory pump that prevents fluid accumulation and keeps the tendons and tissues around the ankle engaged rather than fully passive. These movements do not need to be large or deliberate exercises. Even small, regular movements during sitting produce a meaningful difference to how the ankle feels at the end of a long session.

Getting up and walking briefly every thirty to forty minutes introduces the varied loading and circulatory benefit that sustained sitting suppresses, and reduces the abruptness of the transition from inactivity to more sustained activity later in the day.

Reviewing footwear for the desk day and the commute, particularly if significant walking is involved, tends to produce one of the most direct reductions in ankle load available. Footwear with adequate cushioning and support reduces the impact and compressive load on the ankle joint and the demand on the surrounding tendons with every step.

A brief period of gentle calf stretching and ankle mobility work before sustained walking or standing after a long desk session helps prepare the tissues for the increase in demand rather than transitioning abruptly from inactivity to activity.

Your VIDA programme includes exercises and stretches for the lower leg and ankle designed to support recovery and maintain the tendon resilience and joint mobility that a combination of desk work and daily activity demands.

A brief note on when to get support

Most ankle pain responds well to load management, footwear adjustments, and gradual activity over a few weeks. If ankle pain has been present for more than six weeks without meaningful improvement, is getting progressively worse despite adjustments, or is accompanied by significant swelling, bruising, or an inability to bear weight comfortably, speaking to a physiotherapist or GP is worth doing sooner rather than later.
