RUN & FLY MENS VINTAGE 60S 70S RETRO BLACK BOOTCUT FLARED CORDS
Been looking for years for proper bootcut cords and now found them. Absolutely delighted. Would be great if you could also get in other colours such as navy and grey.....Here''s hoping! I'm 6'5" and the 34" leg length is perfect. Highly recommend.
