FAQs
How do these socks and underwear fit?
The socks feature ribbed cuffs that stay in place without digging in, whilst the boxers have a comfortable elastic waistband with a regular fit. Both are true to size – if you normally wear medium, stick with medium here. The cotton fabric has a slight give but maintains its shape wash after wash.
Can I put these in the washing machine?
Yes, all pieces are machine washable. Wash with similar colours at 30-40 degrees and tumble dry on low if needed. The cotton construction holds up well to regular washing – these are designed to be everyday essentials, not delicate items that need special care.
Are these suitable for intense training sessions?
Absolutely. The breathable cotton keeps air circulating during cardio, weights or circuits. The secure fit means no distractions from slipping socks or uncomfortable waistbands. They work equally well for recovery days, rest days and everything in between.
What's the difference between crew and ankle socks?
Crew socks sit higher on the leg, usually mid-calf, providing more coverage and working well with most trainer styles. Ankle socks sit just above the shoe line, offering a lower profile that's ideal for warmer weather or when you prefer less fabric. Both deliver the same comfort and quality.
How many pairs should I buy?
It depends on how often you train and do laundry. The 5-pack gives you enough rotation for weekday training with a couple of spares. If you prefer doing laundry less frequently or train twice daily, consider multiple packs. The multi-pack format makes stocking up straightforward.
Who designed these products?
Myprotein's in-house design team created this collection, focusing on durability and everyday functionality. They're designed by people who understand training routines and the importance of reliable basics that simply work.
Will the elastic lose its stretch over time?
The elastic waistbands and sock cuffs are built to maintain their tension through regular wear and washing. Proper care helps – avoid excessive heat in the dryer and don't stretch them unnecessarily when putting them on. With normal use, they'll keep their shape for months of regular training.
Can I wear these outside the gym?
Definitely. The clean, classic designs work just as well for daily wear as they do for training. Wear them to work, for weekend errands or simply lounging at home. They're versatile basics that transition seamlessly between all parts of your routine.
