Our 100% Perfect Fit Guarantee

Even the best compression socks are no good if the fit sucks!

While our sizing is true to size and as accurate as possible, sometimes the fit just isn't right.

That's why we have our 100% Perfect Fit Guarantee:

Try our compression socks on at home, wash them and if you're not 100% satisfied with the fit within 30 days of receiving your order, simply send us an email telling us your order number and the size you need, and we'll send you the new size free of charge - no need to return the original product.
