Tiem Womans Pink Cycling Shoes Great Condition Size 8.5 The Slipstream is a performance cycling shoe that doesn't sacrifice the style and comfort of your favourite pair of trainers. With its breathable mesh toe box, slip-on construction, and single-strap closure system, it's the most comfortable shoe you'll ever wear to class. Breast cancer edition Slipstream should fit snug, without much toe-room to account for the normal stretching of the material after several wears. Normal Feet: we recommend you order a half-size down from your normal shoe size (e.g. if you sometimes wear a size 8.5 in running sneakers, but you usually a size 8 in a street shoe, then you'll want to order a size 7.5 in the Slipstream).
