These grey Athletic Propulsion Labs TechLoom Phantom sneakers comprise a low top design, lace-up fastening, branded neoprene tongue, heel pull tab and contrasting rubber sole. The newly developed Techloom upper hosts a comfortable four-way stretch, textured finish and internal cushioning. With technical running shoes such as these Athletic Propulsion Labs trainers, you may just be able to persuade us to sign up for next year’s half marathon. In the meantime, we’ll keep things low key and get that 5K app downloaded for an occasional jog around the block.
