KELDA starts with pure sheep wool, felted by hand and left undyed and untreated, the same simple process used for generations. That plain wool turns out to be remarkably practical: naturally insulating in winter, breathable enough for warm days, and quick to wick moisture so feet stay dry rather than damp. Silk or linen trim and a colorful insole finish each pair, and because every batch of felt is worked slightly differently, no two are ever identical. Comfortable enough for daily wear around the house or out, KELDA is meant to be lived in and to soften, not wear thin, with time.
