Selling a pair of Scarpa Instinct Slipper EU37 (UK4 1/4, according to Scarpa). Used for a dozen indoor boulder problems max, so as new. Finally conceded defeat/admitted they're too small as they haven't stretched at all, hence sale.
£70 posted, but would ideally prefer a swap for the same shoe in EU37.5 (similar condition), or consider Boostics in EU38 (VGC).
