I bought these loafers thinking they would fit since I can wear 6C in 641GOLF, but they were a vice-like fit... The ball joint and instep feel tight, but the heel cup is super tight, and I've gotten blisters that left marks (see photo 8). I couldn't bear the breaking-in process, so I'm selling them. Brand: J.M. WESTON Model: 180 Signature Loafer Last: 41 Size: 6C 25.5cm Color: Black Material: Box Calf Accessories: Shoe bags, box ZOZOMAT Measurements Right Foot Length: 25.2 Right Foot Width: 9.8 Right Instep Height: 6.6 Right Heel Width: 6.5 Right Foot Length: 25.3 Right Foot Width: 9.6 Right Instep Height: 6.9 Right Heel Width: 6.6 The fit is super tight. I purchased these from a major recycle shop about a year ago. I've worn them about 3 times. Neither the lifts nor the soles have been replaced. There's not much creasing at the moccasin stitching, and there are no major scratches that have peeled the grain. I've cleaned them with Collonil Condition Cleaner and applied a thin layer of colorless cream, making it easier to see wrinkles and scratches. The top lifts still have more than half their life left, so you can still wear them without replacing them. Below are the sizes of shoes I own. All of these are my true size, so I hope this helps you with the fit. Alden Barrie Last 7.5D Crockett & Jones 335 Last 6.5E J.M. Weston 31 Last 6D I do not accept cancellations or returns.
