Hi, I've been cycling a few years and recently joined a road cycling club. I've done +/- 60km cycles at about 25km/hr pace with them wearing runners with toe clips. They said I'll ruin my ankles cycling in runners and should get cleats with cycling shoes or get cycling shoes suitable for toe clips. I don't want to get cleats so today bought a pair of Rockrider MTB shoes. I had to buy a 1/2 size bigger than my runners as they are narrow and my feet are really wide. I tried them on the bike and realised that I can fit three fingers between my ankle and the back of the shoe so I don’t think my ankle is getting any support. Is there any chance of my ankles getting injured if I continue cycling with runners and toe cleats? Sorry for being so long winded! Thanks
