About Reiff
Reiff is a fourth-generation German knitwear maker founded in 1939 by Adolf Reiff. The company pioneered washable organic wool products for babies and children in the 1970s—decades before natural fiber childrenswear became mainstream. Today, Reiff manufactures exclusively in Germany with strict organic fiber sourcing, kbT certification (organic livestock farming), and mulesing-free Patagonian merino wool. Every piece is made for durability and designed to be passed between children.
When to Wear
Foundational Wool Layer for Newborns
These booties are a core wardrobe piece for newborns and infants from birth through the first year. They're worn on the feet under pants or layered with other pieces in cool-to-cold weather. Reiff infant booties work as a standalone piece in mild seasons or as a warm base layer under socks in winter.
Temperature range: 15–20°C (59–68°F) and below, depending on layering and activity. On warmer days, pair with lightweight clothing; in cold months, wear as the foundational layer under other socks or inside booties.
The gentle cuffs stay securely in place without tight elastic, making them ideal for newborns with delicate skin and new parents transitioning to wool care.
Materials & Certifications
100% Organic Merino Wool
These booties are knitted from 100% kbT-certified merino wool. The fiber comes from Patagonian organic livestock farming (South America), then processed and knitted in Germany. This is a fine-knit construction with a soft, non-felted texture.

Why Merino for Infant Booties
What Wool Does That Synthetics Don't
Temperature Regulating
Merino wool actively responds to your baby's skin temperature, keeping tiny feet warm in cool weather while remaining breathable. Unlike synthetics, wool adjusts to climate changes throughout the day.
Naturally Breathable
The fiber structure allows moisture vapor to escape, preventing overheating and dampness inside booties. This reduces the risk of sweating and subsequent chilling.
Odor & Bacteria Resistant
Merino wool naturally resists bacterial growth and odor development, meaning these booties need less frequent washing than cotton or synthetic socks—gentle on delicate skin and the environment.
Certified Organic & Sustainable
kbT and GOTS certifications mean zero pesticides, mulesing-free practices, and strict environmental oversight from fiber farming to finished product.
Sizing by Age & Foot Length
Find Your Size
Reiff infant booties are sized by age range and foot length (heel to toe). Measure your baby's foot from the back of the heel to the tip of the longest toe. The cuffs are gently stretchy and do not have tight elastic, so a snug fit is normal.
| Size |
Age Range |
Foot Length |
| Size 0 |
0–3 months |
~10 cm (4 inches) |
| Size 1 |
3–6 months |
~11 cm (4.5 inches) |
| Size 2 |
6–12 months |
~14 cm (5.5 inches) |
Fit note: Reiff booties feature gentle cuffs rather than tight elastic, so there is no "too snug" concern. If your infant is on the larger side for their age, size up one size for comfort during active movement.
Be Informed
Is This Right for Your Baby?
Best For
Newborns and infants who need warm, breathable foot coverage in cool-to-cold weather. These booties work well for parents prioritizing organic fibers, minimal processing, and durability—pieces that last through multiple children. Also ideal for families wanting to avoid synthetic materials and unnecessary washing.
Trade-Offs & Considerations
Wool sensitivity: Fine merino wool at 17–19 microns is soft enough for most babies and sensitive-skinned infants. A small percentage of people still react to wool even at this fineness. If your child has shown wool sensitivity in the past, start with a wool/silk blend as your first wool layer—silk is gentler for very reactive skin.
Price: These are heritage European products at heritage European prices. They're made to last through multiple children, which spreads the investment across years and siblings.
Care routine: Wool requires cold-water washing and air drying. Once you learn the routine, it's simple—but it does differ from typical baby sock care.
Investment Case
A single pair costs more than mass-market baby socks, but these booties are designed for durability and are regularly passed between children. They resist pilling, hold their shape through multiple years of wear, and age well. Over a childhood or across siblings, the per-wear cost is significantly lower than cheaper alternatives.
Gentle Care for Longevity
How to Wash & Maintain
Hand wash or delicate machine cycle Cold water only Wool-specific detergent Lay flat to dry No tumble drying
Washing: Hand wash or use your machine's wool/delicate cycle with cold water and a wool-specific detergent (such as Eucalan or Sonett). Do not rub or agitate vigorously. After washing, gently press water out—never wring. Rinse with cold water until water runs clear.
Drying: Wrap the wet booties in a towel to absorb excess water, then reshape gently and lay flat on a clean, dry surface away from direct heat or sunlight. Air drying takes 24–48 hours.
Frequency: Wool is naturally odor-resistant and rarely needs washing after every wear. Airing booties between wears is often sufficient. With proper care, these booties last for years and are perfect for passing to younger siblings.

Common Questions
FAQ
Are these booties itchy for sensitive skin?
Fine merino at approximately 19 microns is soft and suitable for most babies, including those with sensitive skin. Merino is significantly finer than coarser wool types. However, a small percentage of people are sensitive to all wool, even fine merino. If your baby has reacted to wool before, try a wool/silk blend first—the silk smooths the surface and is gentler.
Can I machine wash these?
Yes, use your machine's wool or delicate cycle with cold water and a wool-specific detergent. Do not use hot water or a standard wash cycle, which can felt and shrink wool. Hand washing is gentler, but a wool cycle is safe if used correctly.
How often should I wash these booties?
Wool is naturally odor-resistant and antimicrobial, so these booties need less frequent washing than cotton or synthetic socks. Airing between wears is often enough. Wash when visibly soiled or after several days of wear. Most families wash wool items every 7–10 days with regular wear.
What's the difference between kbT, GOTS, and IVN BEST?
kbT (kontrolliert biologische Tierhaltung) certifies organic livestock farming with animal welfare standards. GOTS (Global Organic Textile Standard) covers the entire textile processing chain from fiber farming through dyeing and finishing. IVN BEST is a stricter environmental and labor standard set by the International Association of the Natural Textile Industry. Reiff holds all three, ensuring organic fiber sourcing, sustainable processing, and ethical manufacturing.
Are these booties mulesing-free?
Yes. Reiff sources merino wool exclusively from Patagonian farms certified as mulesing-free. Mulesing is a painful surgical procedure performed on sheep to prevent flystrike; mulesing-free farming uses alternative prevention methods. All Reiff products meet this standard.
Can I pass these to a younger sibling?
Absolutely. Reiff booties are designed for durability and longevity. With proper care, they hold their shape and elasticity through multiple children. They age beautifully and are softer with each wash. This durability is part of the value—the cost per child decreases significantly when pieces are passed down.
What if my baby outgrows these before the season ends?
Reiff booties are sized by age and foot length, so you'll likely size up as your baby grows. Keep the smaller sizes for a younger sibling or donate to a family who can use them. Many natural fiber families pass items through community networks because they're built to last.
