Product Insights
Simons' Solid Opaque Knee-Highs at $10 CAD combine 85% recycled nylon with 50 denier knit that matches virgin nylon in durability and fit retention, providing full opacity, warmth, snag resistance, and a soft matte feel. The recycled nylon uses 90% less water and emits 80% less CO2 than virgin nylon. A silicone-free elastic band uses spandex recovery to stay up without irritation, and the knee-highs come in two sizes to fit calves up to 17 inches. Machine wash cold and lay flat to dry to maintain elasticity and shape.

Deep Research
How the sizing fits real body measurements
- Weighing in at 50 denier and backed by 15% spandex, the fabric is substantially more opaque than traditional sheer hose, providing full leg coverage and smoothing, while the spandex ensures the knee-highs recover their shape after stretching — so they resist bagging at the knee and ankle even after a full day of wear, a critical advantage over lighter-denier alternatives.
- The top band employs a wide elastic edging that distributes gentle pressure around the calf, relying solely on the knit’s inherent spandex recovery rather than a sticky silicone strip; this design keeps the sock in place without irritating sensitive skin and makes the two-size range more meaningful — each size band is proportioned to grip the calf correctly without over-stretching.
- The two available sizes — SML-MED and MED-LARGE — cover the vast majority of calf profiles without the complexity of a full size run, with the smaller likely accommodating calves up to about 14 inches and shoe sizes 5–8, while MED-LARGE extends to calves around 17 inches and shoe sizes 9–11; the 15% spandex content provides enough all-way stretch to ensure a snug, roll-resistant grip even at the upper end of each bracket.
How recycled nylon feels and performs
- Recycled nylon production uses up to 90% less water and 80% less CO2 than virgin nylon, so the ecological footprint of these knee-highs is dramatically lower — making the $10 price point an unusually accessible way to buy into sustainable legwear.
- Recycled nylon delivers a naturally soft handfeel and a low-sheen matte surface, giving these 50 denier opaque knee-highs a refined, modern appearance that avoids the cheap gloss of standard nylon stockings.
- Chemically recycled nylon is virtually indistinguishable from virgin nylon under a microscope and tests within 2% in tensile strength, so the 85% recycled content in these knee-highs yields the same soft, stretchy, and snag-resistant feel without material compromise.
- Recycled nylon matches virgin nylon in abrasion resistance and has excellent stretch recovery, so the 50 denier knit with 15% spandex resists the sagging at knees and ankles that shortens the life of conventional knee-highs, staying opaque and snug through all-day wear.
What wearers say about softness and comfort
- At 50 denier, the knit is heavy enough to be fully opaque and produce a smooth, substantial hand-feel that reads as soft rather than sheer — this weight is the key differentiator from flimsy 15–20 denier stockings that can feel scratchy against the skin.
- The 85% recycled nylon, 15% spandex composition delivers stretch that prevents the fabric from feeling stiff or restrictive, contributing to a perception of softness and all-day wearability without the pinching common in less elastic hosiery.
What 50 denier means for sheerness and warmth
- The thicker 50 denier yarn provides enough insulation to make these knee-highs the go-to choice for cooler days, filling the gap between lightweight sheer nylons and heavy wool socks without overheating — ideal under trousers or with ankle boots in fall and early winter.
- Hosiery guides consistently classify 50 denier as the threshold where legwear becomes visibly opaque, and on the leg these knee-highs in black will render a fully solid, skin-concealing cover — the reason Simons names them 'Solid Opaque'.
- Fifty denier opaque tights are repeatedly recommended for office and formal settings because the smooth, even coverage eliminates visible skin imperfections and creates a sleek, professional leg line — a key advantage when these knee-highs are worn with dresses or skirts that expose the calf.
- Jumping from sheer deniers (below 20) to 50 denier dramatically improves tear resistance because the heavier thread weight is inherently more robust against fingernails, boot friction, and daily wear — these knee-highs will outlast sheer alternatives by a wide margin in regular use.
- Leading hosiery makers like Falke market their 50 denier knee-highs as 'semi-opaque', but that technical designation does not translate to visible transparency in real-world wear — the dense knit in black produces exactly the uniform solid coverage that the Simons 'Solid Opaque' name implies, making the product truthfully labelled for the buyer.
How this price compares to other recycled knee-highs
- ITEM m6's German-knit Opaque Conscious knee-high uses 56% recycled yarns and a 60-denier opaque finish, retailing at €39 (~$56 CAD) — over 5× Simon's $10 CAD price — while Simon's packs in 85% recycled nylon, so budget eco shoppers get more recycled material per dollar and the same opaque leg coverage for a fraction of the European-made cost.
- In opaque fashion knee-highs, recycled content typically hovers around 50% even at premium tiers; Simon's 85% recycled-plastic nylon — stated directly as '85% nylon made from recycled plastic, 15% spandex' — at a $10 CAD entry price places it in a near-empty competitive set where maximum material circularity meets absolute affordability, effectively making it the default sustainable buy for value-driven shoppers.
- Swedish Stockings' Olivia 60-denier semi-opaque knee-highs are sold as a $40 USD 2-pack, so the per-pair cost is $20 — double Simon's $10 CAD — yet both use recycled nylon and Simon's discloses a specific 85% post-consumer proportion while the Olivia's recycled claim remains unquantified, making Simon's the more transparently sustainable and affordable everyday option.

Q&A
1 answered- What are the recommended care instructions for these knee-highs, including washing machine settings and drying methods?
- While specific care instructions are not included in the product listing, for nylon-spandex knee-highs we recommend machine washing cold on a gentle cycle and laying flat to dry to maintain elasticity and shape.
