Verified claims
- material
- 87% organic cotton, 12% polyamide, 1% elastane
- fit
- ONE SIZE, with rib knit stretching to fit a range of foot and calf sizes
- fit
- Ribbed cuff holds the sock up through mechanical spring rather than a heavy tight band
- comfort
- Cotton-rich knit breathes and helps regulate temperature, reducing a clammy feel
- comfort
- Cotton absorbs moisture readily but dries slowly and can feel heavy when wet
- material behavior
- Organic cotton is not inherently softer; softness comes from staple length and combing
- durability
- Nylon/polyamide adds abrasion resistance at heel and toe, extending wear versus pure cotton
- material behavior
- 1% elastane supplies the return that cotton rib lacks; without it, cotton sags
- construction
- Reinforced heel and toe with visible seams
- construction
- Continuous rib knit from cuff through instep and upper foot, with elastic ribbed edging
- origin
- Le 31 by Simons exclusive, designed in Canada and made in Portugal
- care
- Machine wash at 30°C
- care
- Do not bleach; do not iron or press
- care
- Wash cold/gentle and air-dry flat to preserve rib recovery; high dryer heat relaxes elasticity
- durability
- Rib stretch is structural, but cotton fibre recovers less than wool; overpulling can hit a stiff limit
- styling
- Five solid colors; black is the functional default that recedes under dark trousers
- styling
- Orange is the high-contrast pick for a deliberate flash at the ankle
- styling
- Brown, green and blue are muted middle options that echo trouser or shoe tones
- value
- All five colors are 22 CAD, ONE SIZE and in stock; choice is color only
- tradeoff
- Ribbed fabric is thicker than flat jersey and may crowd close-fitting dress shoes
- suitable uses
- Best suited to everyday and dress-casual wear, especially with cuffed or cropped trousers

| Solid Rib-Knit Socks: Choose this if you want soft, stretchy crew socks made mostly of organic cotton (87%, with 12% polyamide and 1% elastane), designed in Canada and made in Portugal as a Le 31 by Simons exclusive. The rib-knit design features a wide elastic ribbed cuff, continuous vertical ribbing through the leg and foot, and reinforced heel and toe for everyday wear. They come in Black, Brown, Green, Blue, and Orange, but are offered in one size only, which may not suit shoppers needing a specific fit.[1,2] | Solid Finely Ribbed Socks: Choose these for everyday casual wear if you want soft, comfortable socks that run true to size—reviewers describe them as very comfy with no reported bunching, slipping, or itching, and one size 13 wearer found them comfortable without tightness. They are finely ribbed crew socks made of 80 percent organic cotton with moisture-wicking Drycool polyester and a touch of spandex for stretch, with elastic edging and a reinforced heel and toe. Pick them if you like choosing exact colours to match your wardrobe; buyers report the colours look vibrant and accurate, though this analysis draws on only a few customer reviews.[3,4] | Combed-Cotton Ribbed Socks 3-Pack: Choose these if you want soft everyday crew socks in a cotton-forward blend — they are made of 90% combed cotton with 5% nylon and 5% spandex for stretch, with a ribbed knit cuff and elastic edging. Each pack includes three pairs in an Ivory/Cream Beige color, offered in one size. Note that the foot and toe areas show visible stitching and heel shaping rather than a seamless toe, according to the product images.[5,6] |
