This is the first shoe I bought for rock climbing and I used it exclusively for gym bouldering plus a little bit of outdoor bouldering. This shoe is fantastic for beginner climbers who are looking for a more comfort-based shoe rather than performance-based, so it can be used for longer climbs as well. The rubber isn't super sticky but still retains its tack after months and months of usage, but the shoe does stretch out about a half size, even though it is synthetic leather. There's no point in getting uncomfortable shoes if you are just starting out, so I recommend getting your street shoe size or a half size bigger. You can always go up an additional half size or so for comfort, but keep in mind that after a few months you will need new shoes because your shoes will be too loose.
